We look at the division of 793610 by 85 
The aim is to understand the frequency of 85 in 793610.

Going ahead to step 1:
7 divided by 85 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 85

Let's proceed to step 2:
85 goes into 79 0 times with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 85

Step 3:
The number 85 fits into 793 9 times, leaving a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 765 from 793 to get 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 85

Advancing to step 4:
286 divided by 85 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtracting 255 from 286 leaves us with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 85

On to step 5:
When dividing 311 by 85, we get 3 with a remainder of 56.
The next digit of our result is 3. 
Result so far: 933.0
The remainder is 56 after subtracting 255 from 311.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 85

Going ahead to step 6:
If we divide 560 by 85, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 9336.0
If we subtract 510 from 560, 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.

On to step 7:
500 divided by 85 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 9336.5
Subtract 425 from 500 to 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.

Step 8:
If we divide 750 by 85, we get 8 and a remainder of 70.
The next digit of our result is 8. 
Result so far: 9336.58
Subtracting 680 from 750 leaves us 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.

Step 9:
If we divide 700 by 85, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 9336.588
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 9336.588 and a remainder of 0.002.
