We divide 815266 by 39
Our goal is to divide 815266 by 39.

Advancing to step 1:
If we divide 8 by 39, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 39

Step 2:
39 goes into 81 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 3 after subtracting 78 from 81.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 39

Step 3:
When dividing 35 by 39, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 39

Let's proceed to step 4:
If we divide 352 by 39, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
Deduct 351 from 352 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 39

Let's proceed to step 5:
If we divide 16 by 39, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 2090.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 39

Step 6:
39 can be fit into 166 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 20904.0
If we take 156 away from 166, 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.

Let's proceed to step 7:
If we divide 100 by 39, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 20904.2
Subtracting 78 from 100 leaves us with 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 8:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 20904.25
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 9:
When dividing 250 by 39, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 20904.256
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.

Advancing to step 10:
39 can be fit into 160 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 20904.2564
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.

Advancing to step 11:
When dividing 40 by 39, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 20904.25641
Subtract 39 from 40 to 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 12:
If we divide 10 by 39, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 20904.25641
Subtracting 0 from 10 leaves us 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.

Going ahead to step 13:
100 divided by 39 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 20904.2564102
If we take 78 away from 100, we end up with 22.
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 14:
When dividing 220 by 39, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 20904.25641025
Deduct 195 from 220 and we're left 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.

The final outcome is 20904.25641025, with a leftover of 2.5e-08.
