You have to make the conversion of integer to float before the
division. What you are calculating now is (take number = 998, total =
999)

number/total = 998/999 = 0
number/total*100 = 0*100 = 0
float(number/total*100) = float(0) = 0.0

Change "float(number/total*100)" to "float(number)/total*100" and it
should work:

float(number) = float(998) = 998.0
float(number)/total = 998.0/999 = 0.99899899899899902
float(number)/total*100 = 0.99899899899899902 * 100 = 99.899899899899902
