Pot Bound

I've had this plant for some years now and lately it's been on the kitchen window sill. I'd been wondering why the kitchen was feeling so dark. On a spider hunt I removed the plant which immediately let more light into the room - and I realized that it was about time I subdivided it. Now I have 7 new plants in pots plus 3 pots of roots. I wonder how many I will end up with - and what I will do with them all!
