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