Long Division Method
As we have learnt before, division can be done in different ways.
For example, Fact-o-meter
� Division by zero is not possible.
� We cannot change the order of the
16 ÷ 8 = 2 dividend and divisor in division.
For example, 14 ÷ 2 cannot be
Dividend Divisor Quotient written as 2 ÷ 14.
When we write in long division form, we represent it as:
2 Quotient Divisor 8 16 2 Quotient
Divisor 8 16 Dividend or
Dividend
We use long division for such problems that need more than one step as it is convenient.
Division of 2-digit Number by 1-digit Number
Let us learn how to divide a 2-digit number by a 1-digit number with the help of some
examples.
Let’s Attempt
Example 1: Divide 24 by 2. T O
Solution: Step 1: Divide 2 tens by 2. 1 2
2 tens ÷ 2 = 1 ten 2 2 4
Write 1 as quotient and 2 under tens column and – 2
subtract. 0 4
Step 2: Divide 4 ones by 2. – 4
0
Since 2 × 2 = 4, 4 ÷ 2 = 2
Write 2 as quotient and 4 under ones column
and subtract.
Now, remainder is zero. T O
Thus, 24 ÷ 2 = 12 2 4
3 7 2
Example 2: Divide 72 by 3. – 6
Solution: Step 1: Divide 7 tens by 3. 1 2
Write 2 in the quotient at tens place and write – 1 2
6 (= 3 × 2), below 7. 0
Now, subtract 6 from 7 : 7 – 6 = 1
