/**
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 signed value Dividend by the 64-bit
signed value Divisor and generates a 64-bit signed quotient. If Remainder
is not NULL, then the 64-bit signed remainder is returned in Remainder.
This function returns the 64-bit signed 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
