658015 ÷ 86 
The aim is to understand the frequency of 86 in 658015.

On to step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 86

Step 2:
The number 86 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 86

Advancing to step 3:
The number 86 fits into 658 7 times, leaving a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 602 away from 658, we end up with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 86

Let's proceed to step 4:
The number 86 fits into 560 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 76.0
If we take 516 away from 560, we end up with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 86

Going ahead to step 5:
The number 86 fits into 441 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 765.0
Subtract 430 from 441 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 86

Let's proceed to step 6:
86 can be fit into 115 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 7651.0
The remainder is 29 after subtracting 86 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 86 is 3 with a remainder of 32.
The next digit of our result is 3. 
Result so far: 7651.3
The remainder is 32 after subtracting 258 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
If we divide 320 by 86, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7651.33
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 7651.33 with a remainder of 0.062.
