We're dividing 12128823 by 855 
Our goal is to divide 12128823 by 855.

Let's proceed to step 1:
If we divide 1 by 855, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 855

Going ahead 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.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 855

Going ahead to step 3:
If we divide 121 by 855, we get 0 and a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 855

Advancing to step 4:
If we divide 1212 by 855, we get 1 and a remainder of 357.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 855 from 1212 leaves us with 357.
Fetch the next digit (8) from the dividend, attach it to 357 and continue: 3578 / 855

Let's proceed to step 5:
When dividing 3578 by 855, we get 4 with a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 3420 from 3578 and we're left with 158.
Grab the next digit (8) from the dividend, add it to 158, then carry on: 1588 / 855

Going ahead to step 6:
If we divide 1588 by 855, we get 1 and a remainder of 733.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 733 after subtracting 855 from 1588.
Fetch the next digit (2) from the dividend, attach it to 733 and continue: 7332 / 855

Step 7:
855 can be fit into 7332 8 times, resulting in a remainder of 492.
The number 8 becomes the next digit in our result. 
Result so far: 1418.0
Subtract 6840 from 7332 to get 492.
Include the next digit (3) from the dividend after 492, then repeat: 4923 / 855

Step 8:
855 can be fit into 4923 5 times, resulting in a remainder of 648.
Record the quotient 5 as the next digit in the result. 
Result so far: 14185.0
Subtracting 4275 from 4923 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 9:
855 can be fit into 6480 7 times, resulting in a remainder of 495.
Write down 7 as next digit of the result. 
Result so far: 14185.7
The remainder is 495 after subtracting 5985 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 10:
If we divide 4950 by 855, we get 5 and a remainder of 675.
The next digit of our result is 5. 
Result so far: 14185.75
Subtracting 4275 from 4950 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Let's proceed to step 11:
When dividing 6750 by 855, we get 7 with a remainder of 765.
The number 7 becomes the next digit in our result. 
Result so far: 14185.757
If we subtract 5985 from 6750, we get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Moving on to step 12:
When dividing 7650 by 855, we get 8 with a remainder of 810.
The next digit of our result is 8. 
Result so far: 14185.7578
Subtracting 6840 from 7650 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 13:
When dividing 8100 by 855, we get 9 with a remainder of 405.
Write down 9 as next digit of the result. 
Result so far: 14185.75789
Subtract 7695 from 8100 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 14:
If we divide 4050 by 855, we get 4 and a remainder of 630.
Use 4 as the next digit of our solution. 
Result so far: 14185.757894
Deduct 3420 from 4050 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 15:
6300 divided by 855 is 7 with a remainder of 315.
The number 7 becomes the next digit in our result. 
Result so far: 14185.7578947
If we take 5985 away from 6300, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 16:
When dividing 3150 by 855, we get 3 with a remainder of 585.
The next digit of our result is 3. 
Result so far: 14185.75789473
If we take 2565 away from 3150, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

The final outcome is 14185.75789473, with a leftover of 5.85e-07.
