16 Divides a 64-bit unsigned integer by a 32-bit unsigned integer and
17 generates a 64-bit unsigned result and an optional 32-bit unsigned remainder.
19 This function divides the 64-bit unsigned value Dividend by the 32-bit
20 unsigned value Divisor and generates a 64-bit unsigned quotient. If Remainder
21 is not NULL, then the 32-bit unsigned remainder is returned in Remainder.
22 This function returns the 64-bit unsigned quotient.
24 @param Dividend A 64-bit unsigned value.
25 @param Divisor A 32-bit unsigned value.
26 @param Remainder A pointer to a 32-bit unsigned value. This parameter is
27 optional and may be NULL.
