Tuberous Begonia propagation

I have some pots of tuberous Begonia, which when I need to I usually propagate from stems cuttings in summer, but I notice these pots have many shoots coming and was wondering if now might be a reasonable time to divide the tubers?
According to this http://doityourself.com/stry/… is the suggested time. The pots themselves are full of fibrous roots. Are these perennial roots or annual roots that will be replaced naturally? I.e. can I just chop the root ball, and then the tuber safely up now? All this years shoots are only a cm or so tall so far. The pots were kept in a sheltered cold frame over winter.
