We're dividing 830368 by 86 
The aim is to understand the frequency of 86 in 830368.

Going ahead to step 1:
86 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 86

Moving on to step 2:
86 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 86

Moving on to step 3:
If we divide 830 by 86, we get 9 and a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 56 after subtracting 774 from 830.
Bring next digit (3) of the dividend behind the 56 and repeat the process: 563 / 86

On to step 4:
86 goes into 563 6 times with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 47 after subtracting 516 from 563.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 86

Going ahead to step 5:
The number 86 fits into 476 5 times, leaving a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 965.0
Subtract 430 from 476 to get 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 86

Step 6:
The number 86 fits into 468 5 times, leaving a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 9655.0
Subtracting 430 from 468 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
When dividing 380 by 86, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 9655.4
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 9655.44
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 9655.44 with a remaining 0.016.
