/**
Divides a 64-bit unsigned integer by a 32-bit unsigned integer and
generates a 32-bit unsigned remainder.
This function divides the 64-bit unsigned value Dividend by the 32-bit
unsigned value Divisor and generates a 32-bit remainder. This function
returns the 32-bit unsigned remainder.
@param Dividend A 64-bit unsigned value.
@param Divisor A 32-bit unsigned value.
@return Dividend % Divisor
