bda7fbcc 20 Worker function that Divides a 64-bit signed integer by a 64-bit signed integer and\r
1ea5ca46 21 generates a 64-bit signed result and a optional 64-bit signed remainder.\r
22\r
23 This function divides the 64-bit unsigned value Dividend by the 64-bit\r
24 unsigned value Divisor and generates a 64-bit unsigned quotient. If Remainder\r
25 is not NULL, then the 64-bit unsigned remainder is returned in Remainder.\r
26 This function returns the 64-bit unsigned quotient.\r
27\r
28 @param Dividend A 64-bit signed value.\r
29 @param Divisor A 64-bit signed value.\r
30 @param Remainder A pointer to a 64-bit signed value. This parameter is\r
31 optional and may be NULL.\r
32\r
33 @return Dividend / Divisor\r
