For example 75÷4 so firstly you see how many 4 are there in 7 there's only one right because if there was two 4 in 7 then that will be 8 and that’s over 7 so you can’t do that so obviously there will be one 4 in seven. After That you put the 1 on top and then you do 4 x 1 which will equal to 4 right so you put the 4 in line with the 7 then you do 7-4 which is 3. Therefore you put the 3 down and then you bring down the 5 down and that will be 35 and then you do how many 4 in 35 it will be 8 right so you put the 8 up by the 1. After That you do 4 x 8= 32 then you do 35-32=3 and that will give you 18 R 3 because 18 x 4=72 and you’ll need 3 more to make 75 so that's why they do remainder 3 and this is how it will be setup.
