It's hard to tell from the pic, but it looks like your drain piping may just be shoved down the floor drain (not screwed in). If so, take a Sawzall and cut the pipe above the corroded area and it should come out. If it is screwed in, the only way to get it out without busting up the floor is to cut the pipe above the corroded area, break off what you can, take the sawzall and make some relief cuts and peel it out of the drain. Pipewrenches are useless on 50 year old corroded galvanized pipe.
Next, you'll want to make sure the floor drain isn't clogged by running some water through it. If it is, rod the line out. You can rent the machine at home depot. While you're there, buy a 2' piece of pvc and a fernco the size of your existing washer drain, should be 2", but could be 1 1/2". Once you're sure the floor drain is clear, cut the pvc to length and install using the Fernco.

Profit!
