Easy division by 9


A repeated pattern is produced when a number smaller than 9 is divided by 9.

Example:

1. 7/9 = 0.777... (This will work if the dividend is from 1 to 8 and the divisor is 9)

2. 86/9 = 0.8686... (This will work if the dividend is from 10 to 98 and the divisor is 99)

3. 5/99 = 0.0505... (This will work for dividends 1 to 9 and divisor 99)

4. 594/99 = 0.594594... (This will work for dividends 100 to 998 and divisor 999)

5. 74/999 = 0.074074... (This will work for dividends 10 to 99 and divisor 999)

6. 3/999 = 0.003003... (This will work for dividends 1 to 9 and divisor 999)
