I haven't seen any cpu with a fully pipelined division, but division units are at least partially pipelined in recent-ish cpus. They usually can start a new division well before the previous one has stopped executing.
ALUs in Recent Apple cpus can actually start a new division every other cycle (in addition to having an abnormally low latency), which is very impressive.
