+ 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.
+
+ It is the caller's responsibility to not call this function with a Divisor of 0.
+ If Divisor is 0, then the quotient and remainder should be assumed to be
+ the largest negative integer.
+
+ If Divisor is 0, then ASSERT().
+
+ @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
