Sub-topic : Division by 10,100 and 1000

Division by 10 and 100 and 1000 are explained here step by step. We know the
following facts regarding division process:

1. (i) When any number is divided by 1, the quotient is the number itself.

(a) 8 ÷ 1 = 8

(b) 64 ÷ 1 = 64

(c) 572 ÷ 1 = 572

(ii) When a number (except 0) is divided by itself, the quotient is 1.

(a) 8 ÷8 = 1

(b) 64 ÷ 64 = 1

(c) 572 ÷ 572 = 1

iii) When zero (0) is divided by any number, the quotient is zero (0), but no number can
be divided by zero (0).

(a) 0 ÷ 9 = 0, 0/9 = 0, 0 ÷ 115 = 0, 0/115 = 0

(b) 0 ÷ 0 has no meaning, 10 ÷ 0 has no meaning, 15 ÷ 0 has no meaning.

2. When a number is divided by 10, the digits, except the digit at the one's place, make
the quotient and the digit at one's place becomes the remainder.
Example (i): 48 ÷ 10
