We look at the division of 109339 by 39 
Let's see how many times 39 fits into 109339.

Moving on to step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 39

Let's proceed to step 2:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 39

Going ahead to step 3:
39 can be fit into 109 2 times, resulting in a remainder of 31.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 78 from 109, we get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 39

Advancing to step 4:
The number 39 fits into 313 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 312 from 313, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 39

Going ahead to step 5:
39 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtract 0 from 13 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 39

Going ahead to step 6:
39 can be fit into 139 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 2803.0
The remainder is 22 after subtracting 117 from 139.
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 7:
If we divide 220 by 39, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2803.5
Subtracting 195 from 220 leaves us 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 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: 2803.56
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on 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: 2803.564
If we take 156 away from 160, we end up 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.

On to step 10:
40 divided by 39 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 2803.5641
If we take 39 away from 40, we end up 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:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 2803.5641
The remainder is 10 after subtracting 0 from 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:
The number 39 fits into 100 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2803.564102
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:
If we divide 220 by 39, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2803.5641025
Subtracting 195 from 220 leaves us 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 14:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2803.56410256
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.

After the division, we end up with 2803.56410256 and a remainder of 1.6e-08.
