first you have 7 and 3 and since 2x3 is 6 you get 2 and the remain will be 1 you then have your 3 and the closest one is 4 since 4x3 is 12 you subtract 13-12 which gives you 1 you bring your 8 down and will give you 18 and 6x3 is 18 so gives you the six then lastly is 3 which 3x1 is 3 so gives you the one hopefully that makes sense
