We look at the division of 722165 by 85 
The aim is to understand the frequency of 85 in 722165.

Advancing to step 1:
If we divide 7 by 85, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 85

Moving on to step 2:
85 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 85

Advancing to step 3:
85 goes into 722 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 680 from 722 to get 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 85

Let's proceed to step 4:
The number 85 fits into 421 4 times, leaving a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 340 away from 421, we end up with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 85

Step 5:
85 can be fit into 816 9 times, resulting in a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 849.0
Deduct 765 from 816 and we're left with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 85

Going ahead to step 6:
515 divided by 85 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 8496.0
If we subtract 510 from 515, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8496.0
Subtract 0 from 50 to 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.

Let's proceed to step 8:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8496.05
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
750 divided by 85 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8496.058
The remainder is 70 after subtracting 680 from 750.
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 next digit of our result is 8. 
Result so far: 8496.0588
Subtracting 680 from 700 leaves us 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.

After the division, we end up with 8496.0588 and a remainder of 0.0002.
