+/**\r
+ Worker function that Divides a 64-bit signed integer by a 64-bit signed integer and\r
+ generates a 64-bit signed result and a optional 64-bit signed remainder.\r
+\r
+ This function divides the 64-bit signed value Dividend by the 64-bit\r
+ signed value Divisor and generates a 64-bit signed quotient. If Remainder\r
+ is not NULL, then the 64-bit signed remainder is returned in Remainder.\r
+ This function returns the 64-bit signed quotient.\r
