We look at the division of 855131 by 99 
We're looking to find how many times 99 goes into 855131.

Moving on to step 1:
8 divided by 99 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 99

Moving on to step 2:
The number 99 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 99

On to step 3:
When dividing 855 by 99, we get 8 with a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 792 from 855 and we're left with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 99

On to step 4:
If we divide 631 by 99, we get 6 and a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we subtract 594 from 631, we get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 99

On to step 5:
The number 99 fits into 373 3 times, leaving a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
If we subtract 297 from 373, we get 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 99

On to step 6:
99 goes into 761 7 times with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 8637.0
If we take 693 away from 761, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
When dividing 680 by 99, we get 6 with a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 8637.6
If we subtract 594 from 680, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 8:
860 divided by 99 is 8 with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 8637.68
If we subtract 792 from 860, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
When dividing 680 by 99, we get 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 8637.686
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 10:
The number 99 fits into 860 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 8637.6868
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
The number 99 fits into 680 6 times, leaving a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 8637.68686
If we take 594 away from 680, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 12:
99 can be fit into 860 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 8637.686868
Subtract 792 from 860 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 13:
680 divided by 99 is 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 8637.6868686
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 14:
When dividing 860 by 99, we get 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 8637.68686868
The remainder is 68 after subtracting 792 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 8637.68686868 and a remainder of 6.8e-08.
