We look at the division of 656706 by 85 
The aim is to understand the frequency of 85 in 656706.

Step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 85

On to step 2:
85 can be fit into 65 0 times, resulting in a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 85

Let's proceed to step 3:
85 can be fit into 656 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 61 after subtracting 595 from 656.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 85

Step 4:
85 goes into 617 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtracting 595 from 617 leaves us with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 85

Going ahead to step 5:
85 can be fit into 220 2 times, resulting in a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 772.0
Deduct 170 from 220 and we're left with 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 85

Advancing to step 6:
If we divide 506 by 85, we get 5 and a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 7725.0
Subtracting 425 from 506 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
When dividing 810 by 85, we get 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 7725.9
Subtracting 765 from 810 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
85 can be fit into 450 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 7725.95
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 7725.952
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
800 divided by 85 is 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 7725.9529
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 7725.95294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
100 divided by 85 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 7725.952941
Subtract 85 from 100 to 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 13:
If we divide 150 by 85, we get 1 and a remainder of 65.
The next digit of our result is 1. 
Result so far: 7725.9529411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 7725.9529411 with a remainder of 6.5e-07.
