We look at the division of 818113 by 85 
The aim is to understand the frequency of 85 in 818113.

On to step 1:
85 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 85

Going ahead to step 2:
If we divide 81 by 85, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 85

Step 3:
If we divide 818 by 85, we get 9 and a remainder of 53.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 53 after subtracting 765 from 818.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 85

Going ahead to step 4:
531 divided by 85 is 6 with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtract 510 from 531 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 85

Advancing to step 5:
85 goes into 211 2 times with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 962.0
Subtract 170 from 211 to get 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 85

Step 6:
85 goes into 413 4 times with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 9624.0
Deduct 340 from 413 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
85 can be fit into 730 8 times, resulting in a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 9624.8
If we subtract 680 from 730, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 9624.85
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 9624.858
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
700 divided by 85 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 9624.8588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 9624.8588, with a leftover of 0.0002.
