If Dance of Many leaves the battlefield before its first ability has resolved, its second ability will trigger and do nothing. Then its first ability will resolve and put a token onto the battlefield. That token won't have any connection to a Dance of Many permanent, so it won't be exiled when a Dance of Many leaves the battlefield.
Treat the token as entering as a copy of the chosen creature. If that creature normally gets counters when entering, the token creature gets counters.
The ability is targeted and checks the validity of the target when put on the stack and when resolving. If the creature is not still there when the copy ability resolves, the ability doesn't resolve and no token is put onto the battlefield. This card remains on the battlefield as an enchantment with no token.
