We're dividing 22857 by 86 
The aim is to understand the frequency of 86 in 22857.

Step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 86

Let's proceed to step 2:
22 divided by 86 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 86

Moving on to step 3:
If we divide 228 by 86, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 2.0
If we take 172 away from 228, we end up with 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 86

Moving on to step 4:
565 divided by 86 is 6 with a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 49 after subtracting 516 from 565.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 86

Advancing to step 5:
497 divided by 86 is 5 with a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
If we subtract 430 from 497, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 6:
If we divide 670 by 86, we get 7 and a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 265.7
Deduct 602 from 670 and we're left 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.

Moving on to step 7:
The number 86 fits into 680 7 times, leaving a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 265.77
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 265.77 with a remaining 0.078.
