Spread a good spoonful of refried beans onto each tortilla, add a good scoop of the hamburger mixture, spread it out a bit. You will then wrap it like a burrito. Be careful to not overfill and remember the ends should tuck underneath the rest of the burrito. Lay in your pan one next to the other. Depending on the size of your pan you may need them to overlap slightly. If you are running out of room the cooking spray will make it really easy to squish the burritos so you can add additional ones, or sometimes there is extra room at one edge. It will just depend on how big your pan is.
