Let's divide 12735495 by 39
We're looking to find how many times 39 goes into 12735495.

Advancing to step 1:
39 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 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.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 39

Step 3:
The number 39 fits into 127 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 117 away from 127, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 39

Moving on to step 4:
103 divided by 39 is 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 78 from 103 and we're left with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 39

Going ahead to step 5:
39 goes into 255 6 times with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
Deduct 234 from 255 and we're left with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 39

Let's proceed to step 6:
If we divide 214 by 39, we get 5 and a remainder of 19.
The next digit of our result is 5. 
Result so far: 3265.0
Deduct 195 from 214 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 39

Moving on to step 7:
If we divide 199 by 39, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 32655.0
If we subtract 195 from 199, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 39

Going ahead to step 8:
39 goes into 45 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 326551.0
Subtracting 39 from 45 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
60 divided by 39 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 326551.1
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
39 goes into 210 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 326551.15
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 39, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 326551.153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
39 goes into 330 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 326551.1538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
If we divide 180 by 39, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 326551.15384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 326551.153846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 15:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 326551.1538461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 16:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 326551.15384615
If we take 195 away from 210, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 326551.15384615 with a balance of 1.5e-08.
