4/5. Or, 0.80. Honestly, just use a calculator. People don't have time to do this for you. Oh wait, I just did, didn't I? Oops.
4
Once with a remainder of one
4 with a remainder of 9
Four (4.2424) times.
12 with 4 remaining 64 - 4 = 60 = 5 x 12

How many times does 5 go into 20 ?
5 can go into 5 once
