How do place a accumulator on the footie.

I want to place bet on the prem at the weekend but I have no idea how.

I want to bet on the saturday games and if it all goes well, then the winnings carry over to the sunday games.

Do I go in and write it all out on a slip in the bookies then give it to them, or is it different?

I will most likely be using William Hill as they are closest.
