We look at the division of 522410 by 86 
The aim is to understand the frequency of 86 in 522410.

Let's proceed to step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 86

Moving on to step 2:
When dividing 52 by 86, we get 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 86

Step 3:
The number 86 fits into 522 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 516 from 522 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 86

Going ahead to step 4:
64 divided by 86 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 86

Step 5:
641 divided by 86 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 607.0
Subtracting 602 from 641 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 86

Step 6:
When dividing 390 by 86, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 6074.0
Subtract 344 from 390 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
When dividing 460 by 86, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 6074.5
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 6074.53
Subtracting 258 from 300 leaves us 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.

Step 9:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 6074.534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 6074.5348
If we take 688 away from 760, we end up with 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 11:
If we divide 720 by 86, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 6074.53488
Deduct 688 from 720 and we're left 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 outcome is 6074.53488, with a leftover of 3.2e-05.
