We look at the division of 206272 by 86 
The aim is to understand the frequency of 86 in 206272.

Step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 86

Going ahead to step 2:
The number 86 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 86

On to step 3:
206 divided by 86 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 172 from 206, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 86

Going ahead to step 4:
342 divided by 86 is 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 258 from 342, we get 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 86

Let's proceed to step 5:
The number 86 fits into 847 9 times, leaving a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
If we take 774 away from 847, we end up with 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 86

On to step 6:
If we divide 732 by 86, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 2398.0
If we subtract 688 from 732, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 2398.5
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
86 can be fit into 100 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2398.51
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 2398.511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 2398.511 with a remaining 0.0054.
