okay so I'm not sure if you're allowed to do this in your grade but I'm her sweet you both ways you can do it.
so 68 / 5 v can go into 6 once so then you put down the one about the six then you do 6-5 what you get one bring down the 8 would you get 18 and then 5 goes in the 18 3 times which is 15 - 18 - 15 is 3 so at this point you would have to do 13 which is the epitope where your answer should be remainder 3
the other way is the same thing except don't do remainder 3 put a plant next to 68th and you're 13 then put a0 in bring down the zero when she gets 30 and you know that v can go into 36 times so what the top you point 13.6 and that is basically runs are either one I don't know which one you're allowed to do
