If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 39

Going ahead to step 2:
If we divide 13 by 39, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 39

Let's proceed to step 3:
138 divided by 39 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 21 after subtracting 117 from 138.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 39

Moving on to step 4:
When dividing 210 by 39, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 195 from 210, we get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 39

Advancing to step 5:
39 can be fit into 151 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 353.0
The remainder is 34 after subtracting 117 from 151.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 39

Step 6:
39 can be fit into 347 8 times, resulting in a remainder of 35.
The next digit of our result is 8. 
Result so far: 3538.0
If we take 312 away from 347, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 39

Advancing to step 7:
39 can be fit into 358 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 35389.0
Subtracting 351 from 358 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 39

Let's proceed to step 8:
When dividing 74 by 39, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 353891.0
Deduct 39 from 74 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
39 goes into 350 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 353891.8
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
39 goes into 380 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 353891.89
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
290 divided by 39 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 353891.897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
If we divide 170 by 39, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 353891.8974
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
140 divided by 39 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 353891.89743
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
39 goes into 230 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 353891.897435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 15:
350 divided by 39 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 353891.8974358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 16:
If we divide 380 by 39, we get 9 and a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 353891.89743589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 353891.89743589, with a leftover of 2.9e-08.
