We look at the division of 184240 by 86 
The aim is to understand the frequency of 86 in 184240.

Moving on to step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 86

Going ahead to step 2:
The number 86 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 86

Step 3:
86 can be fit into 184 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 172 away from 184, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 86

Step 4:
122 divided by 86 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 86 from 122, we get 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 86

Let's proceed to step 5:
When dividing 364 by 86, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 214.0
The remainder is 20 after subtracting 344 from 364.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 86

Let's proceed to step 6:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2142.0
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
280 divided by 86 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 2142.3
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
220 divided by 86 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2142.32
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
86 goes into 480 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2142.325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 86 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 2142.3255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 2142.3255 and a remainder of 0.0007.
