Divides a 64-bit unsigned integer by a 64-bit unsigned integer and generates
a 64-bit unsigned result and an optional 64-bit unsigned remainder.
This function divides the 64-bit unsigned value Dividend by the 64-bit
unsigned value Divisor and generates a 64-bit unsigned quotient. If Remainder
is not NULL, then the 64-bit unsigned remainder is returned in Remainder.
This function returns the 64-bit unsigned quotient.
If Divisor is 0, then ASSERT().
@param Dividend A 64-bit unsigned value.
@param Divisor A 64-bit unsigned value.
@param Remainder A pointer to a 64-bit unsigned value. This parameter is
optional and may be NULL.
@return Dividend / Divisor
