1004 divided 39 how do i get the answer

Use this for lojg divisions
39 goes outside of the symbol
1004 goes in
you then realize everything you do is basically the opposite of multiplying
use 34 as your guide and break 1004 into pieces
start with 34÷10
you can't do it so you add the next nunber to the problem
34÷100
well you could divide it completely, but adding and counting the times you did it is a lot easier, or subtracting.
for this sake we will| use subtraction
100-34=66
66-34=32
in your calculator you get 2 and a long decimal, but for this sake you just drop it
to finish this problem off you drop your remainding numbers and figure our what multiplies into what.
