We divide 515800 by 39
Our goal is to divide 515800 by 39.

Going ahead to step 1:
If we divide 5 by 39, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 39

Moving on to step 2:
51 divided by 39 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 39 from 51, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 39

Step 3:
If we divide 125 by 39, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 8 after subtracting 117 from 125.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 39

Going ahead to step 4:
39 can be fit into 88 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
If we subtract 78 from 88, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 39

Let's proceed to step 5:
If we divide 100 by 39, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 1322.0
The remainder is 22 after subtracting 78 from 100.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 39

Going ahead to step 6:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13225.0
Subtract 195 from 220 to 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.

Advancing to step 7:
39 goes into 250 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 13225.6
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.

On to step 8:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 13225.64
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.

Advancing to step 9:
39 can be fit into 40 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 13225.641
Subtracting 39 from 40 leaves us 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 10:
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: 13225.641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 39 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 13225.64102
If we subtract 78 from 100, we 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.

Step 12:
220 divided by 39 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 13225.641025
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.

Let's proceed to step 13:
250 divided by 39 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 13225.6410256
Subtracting 234 from 250 leaves us 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.

Moving on to step 14:
If we divide 160 by 39, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 13225.64102564
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.

The final result is 13225.64102564 with a remainder of 4e-09.
