By multiply your number with 100 you shift result for 2 decimal places.
Eg:
10/3=3.333
If you are using integer, result is 3.
If you multiply 10 with 100, (10*100)/3=333.333, using integer's result is 333. Put dot on in front of second digit, and displayed result is 3.33. And you get your result with 2 decimal places.
This is explained too many times when using ADC to display voltage on input...
