What is division?

Division is splitting a number into equal groups. For example, 12 ÷ 3 means: how many groups of 3 are in 12?
The dividend is the number being divided (the big number). The divisor is the number you divide by (the group size). The quotient is the answer.
You can check a division by multiplying: quotient × divisor = dividend. For example, 12 ÷ 3 = 4, and 4 × 3 = 12.

What is a remainder?

Sometimes a number cannot be split into equal groups exactly. The amount left over is called the remainder.
For example, 13 ÷ 5: 5 goes into 13 twice (2 × 5 = 10), and 3 is left over. So 13 ÷ 5 = 2 remainder 3.
The remainder is always less than the divisor. In 13 ÷ 5, the remainder 3 is less than 5.
You can write a division with a remainder like this: 13 ÷ 5 = 2 R 3. The 'R' means remainder.

Division as sharing and grouping

Sharing means splitting a number into equal groups. For example, share 12 sweets among 3 friends: each gets 4.
Grouping means finding how many groups of a certain size you can make. For example, how many groups of 4 are in 12? Answer: 3 groups.
Both sharing and grouping use division, but they look different in real life.
When there is a remainder, it means you cannot share or group exactly. For example, share 13 sweets among 5 friends: each gets 2, and 3 sweets are left over.

Short division (formal method)

Short division is a quick way to divide a two-digit or three-digit number by a one-digit number.
Write the dividend inside the division bracket and the divisor outside, like this: 5 ⟌ 73.
Divide the first digit: 7 ÷ 5 = 1 remainder 2. Write 1 above the 7, and carry the 2 to the next digit.
Now divide 23 (the carried 2 and the next digit 3) by 5: 23 ÷ 5 = 4 remainder 3. Write 4 above the 3, and the remainder 3 is the final remainder.
So 73 ÷ 5 = 14 R 3. Check: 14 × 5 = 70, plus 3 = 73.

Checking division with multiplication

You can always check a division answer by multiplying the quotient by the divisor and adding the remainder.
The rule is: (quotient × divisor) + remainder = dividend.
For example, 73 ÷ 5 = 14 R 3. Check: (14 × 5) + 3 = 70 + 3 = 73. ✔
If the check does not match, you made a mistake. Go back and try again.

Remainders in real life: round up or down?

In real problems, you often need to decide what to do with the remainder.
Sometimes you round up (add 1 to the quotient) because you need a whole extra group. For example, if 13 people need cars and each car holds 5, you need 3 cars (2 full cars + 1 extra).
Sometimes you round down (ignore the remainder) because you only care about full groups. For example, if you have 13 sweets and each bag holds 5, you can fill 2 full bags.
Always read the question carefully to decide: does the remainder mean you need one more, or can you leave it out?

Factor pairs and multiples

A factor pair is two numbers that multiply to give a target number. For example, 3 and 4 are a factor pair of 12 because 3 × 4 = 12.
A multiple of a number is what you get when you multiply it by a whole number. For example, multiples of 5 are 5, 10, 15, 20, ...
If a number is a multiple of the divisor, the remainder is 0. For example, 15 ÷ 5 = 3 R 0, because 15 is a multiple of 5.
Finding factor pairs helps you see if a division will have a remainder. For example, 12 has factor pairs (1,12), (2,6), (3,4), so 12 ÷ 3 = 4 exactly.

Practice tips

Always write down the remainder clearly, like 'R 3'.
Check your answer with multiplication every time.
When dividing, remember: the remainder must be smaller than the divisor. If it is not, your quotient is too small.
Try real-life problems: sharing snacks, packing items, or grouping objects. This helps you understand remainders.

## Division and Remainders – Quick Revision ### What is division? Division is **sharing** or **grouping** a number into equal parts. The number you divide is the **dividend**. The number you divide by is the **divisor**. The answer is the **quotient**. ### What is a remainder? Sometimes division does not work out exactly. The amount **left over** is called the **remainder**. For example, 43 ÷ 5: 5 goes into 43 eight times (8 × 5 = 40), and 3 is left over. So 43 ÷ 5 = 8 remainder 3. We write: 43 = 8 × 5 + 3. **Rule:** The remainder is always **less than the divisor**. It cannot be equal to or bigger than the divisor. ### How to do short division (formal method) 1. Write the dividend inside the division bracket, divisor outside. 2. Divide the first digit (or first two digits if needed) by the divisor. 3. Write the quotient digit above. 4. Multiply the quotient digit by the divisor, write the product under the dividend digits. 5. Subtract to find the remainder. 6. Bring down the next digit and repeat. 7. When no digits are left, the final remainder is the answer's remainder. **Example:** 73 ÷ 3 - 3 into 7 goes 2 (2 × 3 = 6), remainder 1. - Bring down 3 → 13. 3 into 13 goes 4 (4 × 3 = 12), remainder 1. - So 73 ÷ 3 = 24 remainder 1. Check: 24 × 3 + 1 = 72 + 1 = 73. ### Checking division with multiplication To check a division with remainder: **quotient × divisor + remainder = dividend**. If this is true, your answer is correct. ### Real-life problems: round up or down? When a remainder is left, decide what to do with it based on the question: - If you need **whole groups** (e.g., number of buses), round **up**. - If you only care about **full groups** (e.g., number of full boxes), round **down**. **Example:** 50 children, 8 per bus. 50 ÷ 8 = 6 remainder 2. You need 7 buses (round up). ### Factor pairs and multiples - **Factor pairs** of a number are two numbers that multiply to give that number. For 12: (1,12), (2,6), (3,4). - A **multiple** of a number is the result of multiplying it by a whole number. Multiples of 4: 4, 8, 12, 16, … - If a number divides another with no remainder, it is a **factor** of that number. ### Key formula For division with remainder: **Dividend = Quotient × Divisor + Remainder** Always remember: Remainder < Divisor. Check your answer with multiplication.

dividend: The number being divided. In 43 ÷ 5, 43 is the dividend.
divisor: The number you divide by. In 43 ÷ 5, 5 is the divisor.
quotient: The result of division, ignoring any remainder. In 43 ÷ 5, the quotient is 8.
remainder: The amount left over after division. In 43 ÷ 5, the remainder is 3.
factor pair: Two numbers that multiply together to make a given number. For 12, factor pairs are (1,12), (2,6), and (3,4).
multiple: The result of multiplying a number by a whole number. Multiples of 3 include 3, 6, 9, 12, etc.

What is a remainder in division?

The remainder is the amount left over after dividing. For example, 43 ÷ 5 = 8 with remainder 3, because 5 × 8 = 40 and 43 - 40 = 3.

In the division 43 ÷ 5, what is the quotient and what is the remainder?

The quotient is 8 and the remainder is 3. This is because 5 × 8 = 40 and 43 - 40 = 3.

What does the equation a = q × d + r mean in division?

It means: a is the number you divide (dividend), d is the number you divide by (divisor), q is the quotient, and r is the remainder. The remainder r is always less than the divisor d and not negative.

When you divide 37 by 6, what is the quotient and remainder?

37 ÷ 6 = 6 with remainder 1, because 6 × 6 = 36 and 37 - 36 = 1.

How do you check a division with a remainder using multiplication?

Multiply the quotient by the divisor, then add the remainder. You should get the dividend. For example, 8 × 5 + 3 = 43.

What is the rule for the remainder when dividing by a number?

The remainder must be less than the divisor and not negative. For example, when dividing by 7, the remainder can be 0, 1, 2, 3, 4, 5, or 6.

Divide 89 by 4. What is the quotient and remainder?

89 ÷ 4 = 22 with remainder 1, because 4 × 22 = 88 and 89 - 88 = 1.

What does 'division as sharing' mean?

Division as sharing means splitting a number into equal groups. For example, sharing 12 sweets among 3 friends gives each 4 sweets. If there is a remainder, some sweets are left over.

What does 'division as grouping' mean?

Division as grouping means finding how many groups of a certain size you can make. For example, how many groups of 5 are in 17? You get 3 groups and 2 left over.

In a real problem, when do you round a remainder up?

You round up when you need to have enough for everyone or everything. For example, if 23 children need seats and each bus holds 8, you need 3 buses because 2 buses hold 16 and 3 buses hold 24.

In a real problem, when do you round a remainder down?

You round down when you can only use full groups. For example, if you have 23 apples and each bag holds 8, you can fill 2 full bags and have 7 apples left over.

What is short division?

Short division is a quick way to divide by a one-digit number. You write the dividend and divisor, divide digit by digit, and carry remainders to the next digit. For example, 84 ÷ 3: 8 ÷ 3 = 2 remainder 2, then 24 ÷ 3 = 8, so the answer is 28.

Divide 72 by 5 using short division. What is the quotient and remainder?

72 ÷ 5 = 14 with remainder 2. Because 5 × 14 = 70 and 72 - 70 = 2.

What is a factor pair?

A factor pair is two numbers that multiply together to give a product. For example, 3 and 4 are a factor pair of 12 because 3 × 4 = 12.

List all factor pairs of 24.

The factor pairs of 24 are: 1 and 24, 2 and 12, 3 and 8, 4 and 6.

What is a multiple of a number?

A multiple of a number is the result of multiplying that number by a whole number. For example, multiples of 4 are 4, 8, 12, 16, 20, ...

Is 36 a multiple of 9? How do you know?

Yes, 36 is a multiple of 9 because 9 × 4 = 36. So when you divide 36 by 9, the remainder is 0.

What is the remainder when you divide 100 by 7?

100 ÷ 7 = 14 with remainder 2, because 7 × 14 = 98 and 100 - 98 = 2.

What is the least positive remainder?

The least positive remainder is the smallest non-negative remainder you get when dividing. For example, 43 ÷ 5 gives remainder 3, which is the least positive remainder.

What is the least absolute remainder?

The least absolute remainder is the remainder closest to zero, which can be negative. For example, 43 ÷ 5 can also be written as 9 × 5 - 2, so the least absolute remainder is -2.

How do you find the remainder using long division?

In long division, you divide, multiply, subtract, and bring down digits. The final number left after all digits are used is the remainder. For example, 85 ÷ 4: 4 goes into 8 twice (2), multiply 2×4=8, subtract 8-8=0, bring down 5, 4 goes into 5 once (1), multiply 1×4=4, subtract 5-4=1, so remainder is 1.

What does the modulo operation do?

The modulo operation finds the remainder when you divide one number by another. For example, 17 mod 5 = 2, because 17 ÷ 5 = 3 with remainder 2.

If you have 50 pencils and you put them in packs of 6, how many full packs can you make and how many pencils are left?

You can make 8 full packs because 6 × 8 = 48, and 2 pencils are left over. So 50 ÷ 6 = 8 remainder 2.

A teacher has 35 stickers and wants to give each student 4 stickers. How many students can get stickers and how many stickers are left?

8 students can get 4 stickers each because 4 × 8 = 32, and 3 stickers are left. So 35 ÷ 4 = 8 remainder 3.
