We look at the division of 523783 by 86 
The aim is to understand the frequency of 86 in 523783.

Going ahead to step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 86

Let's proceed to step 2:
If we divide 52 by 86, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 86

On to step 3:
When dividing 523 by 86, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 516 from 523 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 86

Going ahead to step 4:
77 divided by 86 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 86

Let's proceed to step 5:
If we divide 778 by 86, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 609.0
The remainder is 4 after subtracting 774 from 778.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 86

Let's proceed to step 6:
86 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 6090.0
Deduct 0 from 43 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
If we divide 430 by 86, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6090.5
Deduct 430 from 430 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 86 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6090.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 86 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6090.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 6090.5 with a balance of 0.0.
