We look at the division of 12820317 by 855 
We want to divide 12820317 by 855.

Going ahead to step 1:
855 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 855

Let's proceed to step 2:
When dividing 12 by 855, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 855

Going ahead to step 3:
The number 855 fits into 128 0 times, leaving a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Bring next digit (2) of the dividend behind the 128 and repeat the process: 1282 / 855

Let's proceed to step 4:
The number 855 fits into 1282 1 times, leaving a remainder of 427.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 855 from 1282 to get 427.
Include the next digit (0) from the dividend after 427, then repeat: 4270 / 855

Going ahead to step 5:
If we divide 4270 by 855, we get 4 and a remainder of 850.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 850 after subtracting 3420 from 4270.
Bring next digit (3) of the dividend behind the 850 and repeat the process: 8503 / 855

Step 6:
The number 855 fits into 8503 9 times, leaving a remainder of 808.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 808 after subtracting 7695 from 8503.
Grab the next digit (1) from the dividend, add it to 808, then carry on: 8081 / 855

Moving on to step 7:
855 can be fit into 8081 9 times, resulting in a remainder of 386.
The number 9 becomes the next digit in our result. 
Result so far: 1499.0
Subtracting 7695 from 8081 leaves us with 386.
Bring next digit (7) of the dividend behind the 386 and repeat the process: 3867 / 855

Moving on to step 8:
If we divide 3867 by 855, we get 4 and a remainder of 447.
Put 4 as the next digit of the answer. 
Result so far: 14994.0
Deduct 3420 from 3867 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 9:
4470 divided by 855 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 14994.5
Subtracting 4275 from 4470 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
If we divide 1950 by 855, we get 2 and a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 14994.52
Subtracting 1710 from 1950 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
855 goes into 2400 2 times with a remainder of 690.
Record the quotient 2 as the next digit in the result. 
Result so far: 14994.522
Subtracting 1710 from 2400 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

In conclusion, the division gives 14994.522 with a balance of 0.069.
