        This function pops two variables and pushes the quotient of the {\em
        vu.intval} fields of these variables. The resulting pushed variable is
        of type {\em e\_int}.

        It is assumed that the left argument of the division was pushed first;
        therefore, the right argument is popped first. A division by zero leads
        to an error.
