We're dividing 83572828 by 855 
The aim is to understand the frequency of 855 in 83572828.

Let's proceed to step 1:
The number 855 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 855

On to step 2:
When dividing 83 by 855, we get 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 855

Moving on to step 3:
835 divided by 855 is 0 with a remainder of 835.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 835 and we're left with 835.
Append the next digit (7) from the dividend to 835 and continue with: 8357 / 855

On to step 4:
The number 855 fits into 8357 9 times, leaving a remainder of 662.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7695 from 8357 leaves us with 662.
Take the next digit (2) from the dividend and append it to 662, then repeat: 6622 / 855

Moving on to step 5:
The number 855 fits into 6622 7 times, leaving a remainder of 637.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 637 after subtracting 5985 from 6622.
Grab the next digit (8) from the dividend, add it to 637, then carry on: 6378 / 855

Going ahead to step 6:
855 can be fit into 6378 7 times, resulting in a remainder of 393.
Write down 7 as next digit of the result. 
Result so far: 977.0
The remainder is 393 after subtracting 5985 from 6378.
Bring next digit (2) of the dividend behind the 393 and repeat the process: 3932 / 855

Moving on to step 7:
855 goes into 3932 4 times with a remainder of 512.
The next digit of our result is 4. 
Result so far: 9774.0
Deduct 3420 from 3932 and we're left with 512.
Fetch the next digit (8) from the dividend, attach it to 512 and continue: 5128 / 855

Step 8:
855 can be fit into 5128 5 times, resulting in a remainder of 853.
Put 5 as the next digit of the answer. 
Result so far: 97745.0
If we subtract 4275 from 5128, we get 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Going ahead to step 9:
If we divide 8530 by 855, we get 9 and a remainder of 835.
The next digit of our result is 9. 
Result so far: 97745.9
Subtract 7695 from 8530 to get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Step 10:
855 can be fit into 8350 9 times, resulting in a remainder of 655.
Record the quotient 9 as the next digit in the result. 
Result so far: 97745.99
If we take 7695 away from 8350, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

The quotient of the division is 97745.99, and the remainder is 0.655.
