Or, assuming the last d-line (sorry, %o-line) has your expression,

(c2) pickapart(%,2);

                                        e
                                       ---
                                       r t
(e2)                                 %e


(e3)                                Ca k t

                                    Ca k t
(d3)                                -------
                                    e3 + e2
(c3) e3/e2/(e3/e2+1);
