How are 7-card stud tables 8-handed when 7x8=56 and a deck is 52 cards?

A. Half the people on average fold after the first three cards. Seldom do you have everyone going to the river card. However, if that happens, instead of everyone getting dealt a down card, a community card can be used -- face-up, that everyone has access to (almost like in hold 'em). This is how they can deal 7-card stud as an 8-handed game -- and this option almost never comes into play.
