--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---

  _14 = _13 * 32;
  _15 = (long int) _14;
  _2 = _15 /[ex] 32;

I think this will work ....
(simplify
 (exact_div (nop_convert (mult @0 INTEGER_CST@1)) INTEGER_CST@2)
 (if (!TYPE_UNSIGNED (@0)
      && wi::to_wide (@1) == wi::to_wide (@2))
  (convert @0)))
