This division technique can only be used if the divisor could be factorized.
Example 1:
272 ÷ 16 = 17
- Find the factors of the divisor. Choose one of the factors.
16 = 4 × 4 or 16 = 8 × 2
For example, I will use 8 × 2 - Divide the dividend by one of the factor.
272 ÷ 8 = 34 - Divide the quotient from 2. by the second factor.
34 ÷ 2 = 17 - Therefore, the quotient is 17
Note: Try with 4 × 4.
What will happened if the remainder is not zero? Please look at the next example.
Example 2:
275 ÷ 16 = 17 with remainder 3
- 16 = 4 × 4
- 275 ÷ 4 = 68, r. 3
- 68 ÷ 4 = 17
- The quotient is 17, with remainder 3
Note: Try with 2 × 8
