Hi, Judy. Stripping paint off your floor is no different than stripping paint off any other wood. While there are faster strippers, from a safety standpoint I suggest Citristrip. Just glob it on with a cheap, throwaway natural bristle brush. Try to pat it on so it stays in about a 1/8" layer and don't go back trying to make it smooth. I would kind of "checkerboard" it in 2 foot squares so you can easily get to all sides for removal of the gunk and paint. Don't try to do all the squares at one time. Take it slow to start and you can then estimate how much you can do at one time. It is impossible to tell how long it will take to work on your particular floor but when the paint gets wrinkly, it is ready. A putty knife and wide stiff plastic spatula (like for smoothing wallpaper)are good tools for removal. You might also want a plastic mesh sponge pad like Citristrip or 3M make for this. When you have done the checkerboard, go back and fill in the squares. Rinse with mineral spirits. You will probably want to lightly sand before you go on to the finishing and a used sanding screen with a floor buffer will make this go fast.
Don't forget to use chemical resistant gloves and eye protection and follow all the manufacturers directions. Citristrip is non-toxic but can still give you a chemical burn.
