We look at the division of 588947 by 86 
The aim is to understand the frequency of 86 in 588947.

Step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 86

On to step 2:
When dividing 58 by 86, we get 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 86

Advancing to step 3:
If we divide 588 by 86, we get 6 and a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 516 from 588 and we're left with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 86

Let's proceed to step 4:
729 divided by 86 is 8 with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 68.0
The remainder is 41 after subtracting 688 from 729.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 86

Moving on to step 5:
If we divide 414 by 86, we get 4 and a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 684.0
If we take 344 away from 414, we end up with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 86

Advancing to step 6:
When dividing 707 by 86, we get 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 6848.0
If we take 688 away from 707, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 86 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 6848.2
If we subtract 172 from 190, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 86, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6848.22
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 6848.22 and a remainder of 0.008.
