You just do it. Big help I know. There really isn't a question in your question. You cut the old pipe out and replace it. There is a chain cutter available that has a series of cutting wheels in a chain that you tighten down against the pipe and it basically breaks the cast iron pipe cleanly. Use a rubber coupler to connect the cast iron stub with the PVC. This is a short piece of rubber tube the right size to fit the pipe you are working with and is held on with 2 hose clamps. Where the cast goes into the floor or wall, you can take out the last section of cast and insert the PVC into the flare on the piece in the wall or floor and seal it as you would a piece of cast. Without a specific question, that's about all I can help you with.
