  26   Divides a 64-bit signed integer by a 64-bit signed integer and generates a
  27   64-bit signed result and a optional 64-bit signed remainder.
  28
  29   This function divides the 64-bit signed value Dividend by the 64-bit signed
  30   value Divisor and generates a 64-bit signed quotient. If Remainder is not
  31   NULL, then the 64-bit signed remainder is returned in Remainder. This
  32   function returns the 64-bit signed quotient.
  33
  34   If Divisor is 0, then ASSERT().
  35
  36   @param  Dividend  A 64-bit signed value.
  37   @param  Divisor   A 64-bit signed value.
  38   @param  Remainder A pointer to a 64-bit signed value. This parameter is
  39                     optional and may be NULL.
