Er, why have you dug them out? Normally Strawberry plants are left in for three years. Though ours have been in the same place now for the last 18 years.
Now they are out of the ground, you need to plant them in pots and over-winter them in a cold greenhouse. Don't split them though. Any with no roots are not really going to make new roots at this time of year.

You usually propagate them from the runners, and big growers who have room have room put the new plants in a new bed and throw out the old ones after 3 years as OB says, so you have three beds going at once. If you haven't got room just save a small proportion of runners every year and discard the oldest plants if you want to do it by the book, or when they stop fruiting well if you don't.
I hope your plants recover. Another year don't dig them up!

Yes, next year just leave them in Dave. They'll be fine. They're tough plants! :)
