We look at the division of 115395 by 39 
We're looking to find how many times 39 goes into 115395.

Step 1:
39 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 39

On to step 2:
39 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 39

Step 3:
The number 39 fits into 115 2 times, leaving a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 78 from 115 leaves us with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 39

Moving on to step 4:
373 divided by 39 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 22 after subtracting 351 from 373.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 39

Going ahead to step 5:
229 divided by 39 is 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 295.0
Subtracting 195 from 229 leaves us with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 39

Moving on to step 6:
39 goes into 345 8 times with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 2958.0
If we take 312 away from 345, 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 7:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 2958.8
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 39 fits into 180 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 2958.84
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
If we divide 240 by 39, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 2958.846
If we take 234 away from 240, we end up 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.

Let's proceed to step 10:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 2958.8461
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.

Moving on to step 11:
39 goes into 210 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2958.84615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 2958.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
330 divided by 39 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 2958.8461538
Subtracting 312 from 330 leaves us 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 14:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2958.84615384
If we take 156 away from 180, we end up 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.

Our division results in 2958.84615384 with a remaining 2.4e-08.
