-/**
- Worker function that Divides a 64-bit signed integer by a 64-bit signed integer and
- generates a 64-bit signed result and a optional 64-bit signed 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.
-
- @param Dividend A 64-bit signed value.
- @param Divisor A 64-bit signed value.
- @param Remainder A pointer to a 64-bit signed value. This parameter is
- optional and may be NULL.
-
- @return Dividend / Divisor
