The number is divisible by 5 if its last digit is 5 or 0.
Examples:
A number is divisible by 25 if its last two digits are zeros or form a number that is divisible by 25.
Examples:
Only the numbers whose last digit is zero are divided by 10 completely.
Only the numbers whose last two digits are zero are divided by 100.
Only those numbers are divided by 1000, the last three digits are zeros.
To make it easier to divide by 10, 100, and 1000, just cross out the same number of zeros in both numbers.
