Step-by-step explanation:
The first thing you want to do is set the equation in the long division format, that is, with the divisor on the outside left, the dividend inside, and the quotient on top.
Next, move the decimal place to the right twice in both the dividend and divisor. The 4.8 becomes 480 and the 0.39 becomes 39.
Put the decimal straight up from that place into the quotient.
After that, find out how many times 39 goes into 4. That is 0 so put a zero above the 4 in the quotient.
Multiply 39 by 0 and put the answer, 0, beneath the 4 and subtract 4 by that 0. The answer to the 4-0 is 4 put that beneath the 4-0. draw an arrow from the 8 down beside the 4 at the bottom.
Find how many times 39 goes into the new formed 48, 1 time, put the 1 above the 8. multiply 39 by that 1, you get 39. put that under the aforementioned 48, and subtract 48 by 39, you get 9. put that beneath the 9 in the lower 39.
Carry down the 0 in 480 to beside the difference, 9, so that you have 90. find how many times 39 goes into 90, twice, put the 2 above the 0 in 480.
Multiply 39 by that 2. you get 78 put that below the 90 and subtract, you get 12 add a 0 to the 480, so that you have 480.0, Then carry that 0 down to beside the 12 so that you have 120.
Find how many times 39 goes into 120, thrice, put that 3 above the 0 after the decimal that you moved up int the quotient. Your quotient so far should be 012.3.
Multiply 39 by the 3, 117, put that below the 120, and subtract. You should wind up with 3. put another 0 at the end of 480.0 so that it becomes 480.00. this puts you in the thousandths place. Bring that 0 down to beside the 3 so it becomes 30.
Find how many time 39 goes into 30, 0 times. Put that 0 above the thousandths place in 480.00.
Multiply 39 by 0, 0, put that below the 30, and subtract. Obviously you should get 30. Put that below the 30-0.
Put one last 0 behind the 480, so that you have 480.000. Cary that down to beside the last 30, so it becomes 300.
Find how many times 39 goes into 300, 7 times, put that in the ten-thousandths place of your quotient.
Your quotient should be 012.307
Round that to the thousandth place to get 12.31. This is your final answer.
