when i divide it on the calculator, the answer is 0.125. But I don't know how to get that answer by hand because I thought the answer would be 8.
so in the calculator you are doing 5/40 which is 1/8 and is 0.125
by hand you are doing 40 divided by 5
when using long division you want the number you are dividing by out side the line and under the line is 5
such as 40 | 5
now how many times does 40 go into 5 0 times
now we add a 0 and we know our answer is going to be a decimal
how many times does 40 go into 50 1 time
now we have 0.1 with remainder 10 now we add a 0 and have 40 | 100 how many times does 40 go into 100
now we have 0.12 and we have remainder 20 so we add another 0 and get how many times does 40 gointo 200 it is 5
our answer is 0.125. with remainder 0 which means this is our final answer.
40/5=8 and 5/40=0.125
