We divide 391120 by 39
We want to divide 391120 by 39.

Let's proceed to step 1:
The number 39 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 39

Going ahead to step 2:
39 can be fit into 39 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 39, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 39

Moving on to step 3:
39 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 39

On to step 4:
11 divided by 39 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 11 to get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 39

Going ahead to step 5:
39 goes into 112 2 times with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 1002.0
The remainder is 34 after subtracting 78 from 112.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 39

Moving on to step 6:
If we divide 340 by 39, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 10028.0
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
280 divided by 39 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10028.7
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 10028.71
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
39 can be fit into 310 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 10028.717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
If we divide 370 by 39, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 10028.7179
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 10028.71794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
39 goes into 340 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 10028.717948
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 39 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 10028.7179487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
70 divided by 39 is 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 10028.71794871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 10028.71794871, with a leftover of 3.1e-08.
