830085 divided by 86 
The aim is to understand the frequency of 86 in 830085.

Advancing to step 1:
8 divided by 86 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 86

Step 2:
When dividing 83 by 86, we get 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 86

On to step 3:
The number 86 fits into 830 9 times, leaving a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 774 from 830, we get 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 86

Moving on to step 4:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 96.0
Deduct 516 from 560 and we're left with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 86

Moving on to step 5:
86 goes into 448 5 times with a remainder of 18.
The next digit of our result is 5. 
Result so far: 965.0
Subtracting 430 from 448 leaves us with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 86

Advancing to step 6:
86 can be fit into 185 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 9652.0
If we subtract 172 from 185, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 86, we get 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 9652.1
If we take 86 away from 130, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
440 divided by 86 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 9652.15
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
86 goes into 100 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 9652.151
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
86 goes into 140 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 9652.1511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 9652.1511 with a remaining 0.00054.
