Sub-topic-7:- 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) 7 ÷ 1 = 7
(b) 53 ÷ 1 = 53
(c) 275 ÷ 1 = 275
(ii) When a number (except 0) is divided by itself, the quotient is 1.
(a) 7 ÷7 = 1
(b) 53 ÷ 53 = 1
(c) 275 ÷ 275 = 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 ÷ 8 = 0, 0/8 = 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
