+/**
+  Divides a 64-bit unsigned integer by a 32-bit unsigned integer and
+  generates a 64-bit unsigned result and an optional 32-bit unsigned remainder.
+
+  This function divides the 64-bit unsigned value Dividend by the 32-bit
+  unsigned value Divisor and generates a 64-bit unsigned quotient. If Remainder
+  is not NULL, then the 32-bit unsigned remainder is returned in Remainder.
+  This function returns the 64-bit unsigned quotient.
+
+  @param  Dividend  A 64-bit unsigned value.
+  @param  Divisor   A 32-bit unsigned value.
+  @param  Remainder A pointer to a 32-bit unsigned value. This parameter is
+                    optional and may be NULL.
+
+  @return Dividend / Divisor
