   * Name: div
   *
   * Description:
   *   The div() function computes the quotient and remainder of the division
   *   of the numerator 'numer' by the denominator 'denom". If the division is
   *   inexact, the resulting quotient is the integer of lesser magnitude that
   *   is the nearest to the algebraic quotient. If the result cannot be
   *   represented, the behavior is undefined; otherwise, quot * denom + rem
   *   will equal 'numer'.
   *
   * Input Parameters:
   *   numer - Numerator of the Division
   *   denom - Denominator of the division
   *
   * Returned Value:
   *   The result of the devision represent as values of type div_t
   *
