We're dividing 800331 by 86 
The aim is to understand the frequency of 86 in 800331.

Let's proceed to step 1:
8 divided by 86 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 86

Step 2:
When dividing 80 by 86, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 86

Advancing to step 3:
If we divide 800 by 86, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 774 from 800 and we're left with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 86

Advancing to step 4:
The number 86 fits into 263 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 93.0
The remainder is 5 after subtracting 258 from 263.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 86

Going ahead to step 5:
If we divide 53 by 86, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 930.0
If we take 0 away from 53, we end up with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 86

Moving on to step 6:
When dividing 531 by 86, we get 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 9306.0
If we subtract 516 from 531, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
86 goes into 150 1 times with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 9306.1
If we take 86 away from 150, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
If we divide 640 by 86, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 9306.17
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9306.174
Subtract 344 from 380 to get 36.
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 10:
If we divide 360 by 86, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9306.1744
The remainder is 16 after subtracting 344 from 360.
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 9306.1744 with a remaining 0.00016.
