Detailed Description

Helper for dividing several small integers by the same value. Note that there is no point using this class is the divisor is a compile-time constant, since the compiler should be smart enough to do this automatically. Building a QuickSmallDivision object costs an integer division, but each call to DivideByDivisor will only do an integer multiplication and a shift.

This class always return the exact value of the division for all possible values of dividend and divisor.
