We're dividing 749681 by 85 
The aim is to understand the frequency of 85 in 749681.

Advancing to step 1:
When dividing 7 by 85, we get 0 with a remainder of 7.
Write down 0 as next digit of the 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

Let's proceed to step 2:
74 divided by 85 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 85

Going ahead to step 3:
749 divided by 85 is 8 with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 69 after subtracting 680 from 749.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 85

Advancing to step 4:
If we divide 696 by 85, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 16 after subtracting 680 from 696.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 85

Advancing to step 5:
85 goes into 168 1 times with a remainder of 83.
The next digit of our result is 1. 
Result so far: 881.0
Deduct 85 from 168 and we're left with 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 85

Let's proceed to step 6:
When dividing 831 by 85, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 8819.0
If we take 765 away from 831, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
The number 85 fits into 660 7 times, leaving a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 8819.7
The remainder is 65 after subtracting 595 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
The number 85 fits into 650 7 times, leaving a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 8819.77
Deduct 595 from 650 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 8819.77 with a remainder of 0.055.
