We divide 125140 by 39
We're looking to find how many times 39 goes into 125140.

Going ahead to step 1:
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: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 39

On to step 2:
The number 39 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 39

On to step 3:
39 can be fit into 125 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 117 from 125 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 39

Step 4:
39 goes into 81 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 78 from 81 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 39

On to step 5:
39 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 320.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 39

Going ahead to step 6:
340 divided by 39 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 3208.0
If we take 312 away from 340, we end up 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.

Let's proceed to step 7:
280 divided by 39 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 3208.7
Subtracting 273 from 280 leaves us 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.

Moving on to step 8:
If we divide 70 by 39, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 3208.71
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.

Advancing to step 9:
When dividing 310 by 39, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 3208.717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
39 goes into 370 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 3208.7179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
39 goes into 190 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 3208.71794
Subtracting 156 from 190 leaves us with 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:
When dividing 340 by 39, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 3208.717948
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.

On to step 13:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 3208.7179487
Deduct 273 from 280 and we're left 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 14:
If we divide 70 by 39, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 3208.71794871
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 result is 3208.71794871 with a remainder of 3.1e-08.
