*div_t div(int numer, int denom) - do signed divide
*
*Purpose:
*       This routine does an divide and returns the results.
*
*Entry:
*       int numer - Numerator passed in on stack
*       int denom - Denominator passed in on stack
*
*Exit:
*       returns quotient and remainder in structure
*
*Exceptions:
*       No validation is done on [denom]* thus, if [denom] is 0,
*       this routine will trap.
