562310 divided by 86 
The aim is to understand the frequency of 86 in 562310.

On to step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 86

Going ahead to step 2:
The number 86 fits into 56 0 times, leaving a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 86

Advancing to step 3:
If we divide 562 by 86, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 46 after subtracting 516 from 562.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 86

Let's proceed to step 4:
The number 86 fits into 463 5 times, leaving a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 33 after subtracting 430 from 463.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 86

Step 5:
The number 86 fits into 331 3 times, leaving a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 653.0
If we take 258 away from 331, we end up with 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 86

Moving on to step 6:
If we divide 730 by 86, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 6538.0
Deduct 688 from 730 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 6538.4
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 6538.48
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 6538.488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 6538.488 with a remainder of 0.0032.
