We're dividing 342081 by 39 
We want to divide 342081 by 39.

Advancing to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 39

Advancing to step 2:
39 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 39

On to step 3:
39 can be fit into 342 8 times, resulting in a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 312 away from 342, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 39

Moving on to step 4:
If we divide 300 by 39, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 273 from 300 and we're left with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 39

Moving on to step 5:
39 can be fit into 278 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 877.0
The remainder is 5 after subtracting 273 from 278.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 39

Going ahead to step 6:
If we divide 51 by 39, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 8771.0
Subtract 39 from 51 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 39 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 8771.3
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8771.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
39 goes into 300 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 8771.307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
If we divide 270 by 39, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 8771.3076
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
360 divided by 39 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 8771.30769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
When dividing 90 by 39, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 8771.307692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 39 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 8771.3076923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
The number 39 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 8771.3076923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 8771.3076923 with a remainder of 3e-08.
