Actually, there is a movie by Brian De Palma called "Body Double" that goes into the process with some practical detail. Essentially, they have a set of markers (sometimes with a hidden support structure). They move one actor out of the scaffold and then move the next one in ... making sure that the hands, feet, navel .... whatever .... are exactly where they need to be with the markers.
Then they start shooting again. If push comes to shove, they can always clean things up in post processing.
