Thats Ok I did the same thing, thats why I couldnt work out how the heck you get /100 from one of these.
I need 50Kc and 10Kc from 10Mc, so /100 with one '390, then /2 with one quarter of a '390, and /5 with t'other quarter, that'll get me what I need, not sure if the 10kc will be a square wave or not.
My original thought was /100 then /2 to get 50Kc, and /100 then /10 to get 10Kc, but seeing as these things are not synchronous /2 and /5 might be better phase wise.
