Step 1 of 4
- 45 sits in the tens and ones columns.
- Share into 10.
- Every digit moves one column right.
- The digits now read 4.5.
The rule
Dividing by 10, 100 or 1000 moves every digit right. Each digit moves one column for each zero.
A digit one column right is worth one tenth as much.
Seen another way, the point moves left by the same count. Open a new column past the point if a digit needs it.
It is the same move as times ten, in the opposite direction.
250 paise ÷ 100 is ₹2.50. There are 100 paise in a rupee. Two zeros, so each digit moves 2 columns right: 250 becomes 2.50.
