855717 divided by 85 
The aim is to understand the frequency of 85 in 855717.

Let's proceed to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 85

Advancing to step 2:
85 can be fit into 85 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 85 from 85 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 85

Advancing to step 3:
85 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 85

Advancing to step 4:
85 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 85

Moving on to step 5:
85 can be fit into 571 6 times, resulting in a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 1006.0
If we take 510 away from 571, we end up with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 85

Moving on to step 6:
If we divide 617 by 85, we get 7 and a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 10067.0
The remainder is 22 after subtracting 595 from 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 85, we get 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 10067.2
Subtracting 170 from 220 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10067.25
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.

Going ahead to step 9:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 10067.258
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 10067.2588
Deduct 680 from 700 and we're left 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.

Our division results in 10067.2588 with a remaining 0.0002.
