/* mpn_divrem_1(quot_ptr, qsize, dividend_ptr, dividend_size, divisor_limb) --
   Divide (DIVIDEND_PTR,,DIVIDEND_SIZE) by DIVISOR_LIMB.
   Write DIVIDEND_SIZE limbs of quotient at QUOT_PTR.
   Return the single-limb remainder.
   There are no constraints on the value of the divisor.

   QUOT_PTR and DIVIDEND_PTR might point to the same limb.
