Let's divide 339634 by 39
Our goal is to divide 339634 by 39.

Step 1:
39 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 39

Moving on to step 2:
If we divide 33 by 39, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 39

On to step 3:
39 can be fit into 339 8 times, resulting in a remainder of 27.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 27 after subtracting 312 from 339.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 39

Advancing to step 4:
When dividing 276 by 39, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 273 away from 276, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 39

On to step 5:
39 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
If we take 0 away from 33, we end up with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 39

On to step 6:
334 divided by 39 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8708.0
Subtract 312 from 334 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.

Going ahead to step 7:
When dividing 220 by 39, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 8708.5
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.

On to step 8:
If we divide 250 by 39, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 8708.56
Deduct 234 from 250 and we're left 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.

Step 9:
When dividing 160 by 39, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 8708.564
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.

Let's proceed to step 10:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 8708.5641
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
39 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 8708.5641
If we take 0 away from 10, we end up 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.

Advancing to step 12:
39 goes into 100 2 times with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 8708.564102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
39 goes into 220 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8708.5641025
If we subtract 195 from 220, we get 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.
The number 6 becomes the next digit in our result. 
Result so far: 8708.56410256
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.

The final outcome is 8708.56410256, with a leftover of 1.6e-08.
