We're dividing 745855 by 85 
The aim is to understand the frequency of 85 in 745855.

Step 1:
85 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 85

Advancing to step 2:
85 can be fit into 74 0 times, resulting in a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 85

Let's proceed to step 3:
745 divided by 85 is 8 with a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 680 from 745 leaves us with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 85

Moving on to step 4:
If we divide 658 by 85, we get 7 and a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 595 from 658 leaves us with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 85

Step 5:
When dividing 635 by 85, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 877.0
If we take 595 away from 635, we end up with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 85

Let's proceed to step 6:
If we divide 405 by 85, we get 4 and a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 8774.0
If we subtract 340 from 405, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
If we divide 650 by 85, we get 7 and a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 8774.7
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.

Let's proceed to step 8:
85 can be fit into 550 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 8774.76
Subtracting 510 from 550 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 85 fits into 400 4 times, leaving a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 8774.764
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 8774.7647
Subtract 595 from 600 to 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.

Let's proceed to step 11:
When dividing 50 by 85, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8774.7647
If we subtract 0 from 50, 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 12:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8774.764705
If we take 425 away from 500, we end up 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.

Going ahead to step 13:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8774.7647058
If we subtract 680 from 750, we get 70.
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 14:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8774.76470588
If we take 680 away from 700, we end up 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.

In conclusion, the division gives 8774.76470588 with a balance of 2e-08.
