Division by 10, 100 and 1000

Observe the following patterns

Dividing multiple of 10 by 10

10 ÷ 10 = 1 [cancel 0 from both : 10 ÷ 10 = 1 ÷ 1 = 1]

30 ÷ 10 = 3 [cancel 0 from both : 30 ÷ 10 = 3 ÷ 1 = 3]

240 ÷ 10 = 24 [cancel 0 from both : 240 ÷ 10 = 24 ÷ 1 = 24]

4210 ÷ 10 = 421 [cancel 0 from both : 4210 ÷ 10 = 421 ÷ 1 = 421]

Dividing multiple of 100 by 100

100 ÷ 100 = 1 [cancel 00 from both : 100 ÷ 100 = 1 ÷ 1 = 1]

500 ÷ 100 = 5 [cancel 00 from both : 500 ÷ 100 = 5 ÷ 1 = 5]

2300 ÷ 100 = 23 [cancel 00 from both : 2300 ÷ 100 = 23 ÷ 1 = 23]

71400 ÷ 100 = 714 [cancel 00 from both : 71400 ÷ 100 = 714 ÷ 1 = 714]

Dividing multiple of 1000 by 1000

1000 ÷ 1000 = 1 [cancel 000 from both : 1000 ÷ 1000 = 1 ÷ 1 = 1]

7000 ÷ 1000 = 7 [cancel 000 from both : 7000 ÷ 1000 = 7 ÷ 1 = 7]

34000 ÷ 1000 = 34 [cancel 000 from both : 34000 ÷ 1000 = 34 ÷ 1 = 34]

451000 ÷ 1000 = 451 [cancel 000 from both : 451000 ÷ 1000 = 451 ÷ 1 = 451]

Dividing any number by 10

93 ÷ 10 quotient = 9, remainder = 3.

234 ÷ 10 quotient = 23, remainder = 4.

3417 ÷ 10 quotient = 341, remainder = 7.

[remainder = ones digit, quotient = remaining number]
