  18   Divides a 64-bit signed integer by a 64-bit signed integer and generates a
  19   64-bit signed result and a optional 64-bit signed remainder.
  20
  21   This function divides the 64-bit signed value Dividend by the 64-bit signed
  22   value Divisor and generates a 64-bit signed quotient. If Remainder is not
  23   NULL, then the 64-bit signed remainder is returned in Remainder. This
  24   function returns the 64-bit signed quotient.
  25
  26   If Divisor is 0, then ASSERT().
  27
  28   @param  Dividend  A 64-bit signed value.
  29   @param  Divisor   A 64-bit signed value.
  30   @param  Remainder A pointer to a 64-bit signed value. This parameter is
  31                     optional and may be NULL.
