Division 81

When we write in long division form, we represent it as:

2 Quotient 8 16 2 Quotient
Divisor 8 16 Dividend or Divisor Dividend

We use long division for such problems that need more than one step as it is convenient.
Let us divide 24 by 2.
T O
Step 1: Write 24 in expanded form.
1
24 = 2 tens + 4 ones 2 2 4

Step 2: Divide 2 tens by 2. – 2

2 tens ÷ 2 = 1 ten 0

Write 1 as quotient and 2 under tens column and subtract.

Step 3: Divide 4 ones by 2.
T O
Since 2 × 2 = 4 1 2

4 ÷ 2 = 2 2 2 4

Write 2 as quotient and 4 under ones column and subtract. – 2
0 4
Now, remainder is zero.
– 4
Hence, 24 ÷ 2 = 12 0

Checking Division

1 2
× 2 If Quotient × Divisor = Dividend,

2 4 your answer is correct.

Thus, 12 × 2 = 24. Hence, answer is correct.
