We look at the division of 135976 by 39 
Let's see how many times 39 fits into 135976.

Advancing to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 39

Advancing to step 2:
13 divided by 39 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 39

Step 3:
When dividing 135 by 39, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 117 from 135, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 39

Moving on to step 4:
189 divided by 39 is 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 156 from 189 and we're left with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 39

Let's proceed to step 5:
39 goes into 337 8 times with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 348.0
Subtract 312 from 337 to get 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 39

Let's proceed to step 6:
256 divided by 39 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 3486.0
Subtract 234 from 256 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3486.5
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
250 divided by 39 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 3486.56
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
160 divided by 39 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3486.564
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3486.5641
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
10 divided by 39 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3486.5641
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 39, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 3486.564102
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3486.5641025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
If we divide 250 by 39, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3486.56410256
If we take 234 away from 250, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 3486.56410256 and a remainder of 1.6e-08.
