We look at the division of 87722660 by 855 
We want to divide 87722660 by 855.

Step 1:
If we divide 8 by 855, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 855

Advancing to step 2:
The number 855 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Bring next digit (7) of the dividend behind the 87 and repeat the process: 877 / 855

On to step 3:
855 goes into 877 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 855 from 877 to get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 855

Advancing to step 4:
The number 855 fits into 222 0 times, leaving a remainder of 222.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 222, we end up with 222.
Append the next digit (2) from the dividend to 222 and continue with: 2222 / 855

Let's proceed to step 5:
The number 855 fits into 2222 2 times, leaving a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 512 after subtracting 1710 from 2222.
Include the next digit (6) from the dividend after 512, then repeat: 5126 / 855

Let's proceed to step 6:
855 can be fit into 5126 5 times, resulting in a remainder of 851.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
If we take 4275 away from 5126, we end up with 851.
Fetch the next digit (6) from the dividend, attach it to 851 and continue: 8516 / 855

Step 7:
855 can be fit into 8516 9 times, resulting in a remainder of 821.
The number 9 becomes the next digit in our result. 
Result so far: 10259.0
The remainder is 821 after subtracting 7695 from 8516.
Bring next digit (0) of the dividend behind the 821 and repeat the process: 8210 / 855

On to step 8:
855 goes into 8210 9 times with a remainder of 515.
The number 9 becomes the next digit in our result. 
Result so far: 102599.0
The remainder is 515 after subtracting 7695 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 9:
If we divide 5150 by 855, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 102599.6
Subtracting 5130 from 5150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
The number 855 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 102599.6
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
855 goes into 2000 2 times with a remainder of 290.
Put 2 as the next digit of the answer. 
Result so far: 102599.602
If we take 1710 away from 2000, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 12:
855 can be fit into 2900 3 times, resulting in a remainder of 335.
The next digit of our result is 3. 
Result so far: 102599.6023
If we subtract 2565 from 2900, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 13:
3350 divided by 855 is 3 with a remainder of 785.
Write down 3 as next digit of the result. 
Result so far: 102599.60233
If we take 2565 away from 3350, we end up with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

In conclusion, the division gives 102599.60233 with a balance of 0.000785.
