Ok, What you want can be done, but you may want to check your local electrical code to see if: 1 you can do the wiring, and 2, see if it's legal. Sometimes in visiting with an electrician can tell you, or even better you can hire one.
You need to remove the 220 breaker from the panel. Take off both wires. Depending on what size 110 wire size your stove requires you'll need to install a 15 amp for 14/2 wire and 20 amp for 12/2. Again check your code for proper wire sizing to breakers. Now you can take one of the wires you removed from the 220 breaker and attached it to the single pole 110 breaker. The other wire put a wire-nut on it, tape it on and mark it as abandoned, and where/what it is. That wire can be left sitting againt the inside of the panel box. Now the trick is you'll need to find the other end of the wire. If the wires are exposed where the stove is, and are separated from one another as to not touch each other or to ground, then turn on your breaker, and with a meter test the black wires with one meter line on the neutral. It it lights, or moves the meter it's hot. Turn off the breaker, and resume back to the stove. The wire not being used, wire-nut it, and tape & mark it as such. Now you can tie into the stove with the required 110 wiring for your stove. Tie the black to black, White to white (neutral) and green-bare wire to ground. As for the electrical box where you tied in the wiring, you'll need to put a cover plate on it so your new wire will have to come from the side of the box (if possible) or the cover plate will have to have a hole in the middle for a box connector.
Any thing else, let me know. Again check with you local electrical laws. If your state allows you to do the job yourself, remember that the bar behind the breakers are "live" and do treat electricity with respect.
