We look at the division of 749168 by 85 
The aim is to understand the frequency of 85 in 749168.

Going ahead to step 1:
7 divided by 85 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 85

Moving on to step 2:
85 goes into 74 0 times with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 85

Moving on to step 3:
When dividing 749 by 85, we get 8 with a remainder of 69.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 680 from 749 and we're left with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 85

Let's proceed to step 4:
The number 85 fits into 691 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 11 after subtracting 680 from 691.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 85

Advancing to step 5:
If we divide 116 by 85, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 881.0
If we take 85 away from 116, we end up with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 85

Step 6:
When dividing 318 by 85, we get 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 8813.0
If we subtract 255 from 318, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
630 divided by 85 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 8813.7
Subtract 595 from 630 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.

On to step 8:
350 divided by 85 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 8813.74
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 85, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 8813.741
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
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: 8813.7411
Deduct 85 from 150 and we're left 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.

After the division, we end up with 8813.7411 and a remainder of 0.00065.
