/**\r
  Divides a 64-bit signed integer by a 64-bit signed integer and generates a\r
  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 signed\r
  value Divisor and generates a 64-bit signed quotient. If Remainder is not\r
  NULL, then the 64-bit signed remainder is returned in Remainder. This\r
  function returns the 64-bit signed quotient.\r
\r
  It is the caller's responsibility to not call this function with a Divisor of 0.\r
  If Divisor is 0, then the quotient and remainder should be assumed to be\r
  the largest negative integer.\r
\r
  If Divisor is 0, then ASSERT().\r
\r
  @param  Dividend  A 64-bit signed value.\r
