This question can be interpreter as: If an integer is divided by 100, how many digits will be there after the decimal point?
The answer is that there will be 2 digits.
E.g. In a single digit number 6, 6 ÷ 100 = 0.06
In a double digit number 23, 23 ÷ 100 = 0.23
In a triple digit number 186, 186 ÷ 100 = 1.86
And so on...
