288797 divided by 85 
The aim is to understand the frequency of 85 in 288797.

Step 1:
85 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 85

Step 2:
28 divided by 85 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 85

Going ahead to step 3:
85 goes into 288 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 255 from 288, we get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 85

Going ahead to step 4:
The number 85 fits into 337 3 times, leaving a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtract 255 from 337 to get 82.
Include the next digit (9) from the dividend after 82, then repeat: 829 / 85

On to step 5:
85 can be fit into 829 9 times, resulting in a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 339.0
The remainder is 64 after subtracting 765 from 829.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 85

Step 6:
When dividing 647 by 85, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 3397.0
Deduct 595 from 647 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
The number 85 fits into 520 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 3397.6
If we take 510 away from 520, 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 8:
If we divide 100 by 85, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 3397.61
If we subtract 85 from 100, we 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.

On to step 9:
If we divide 150 by 85, we get 1 and a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 3397.611
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 3397.611 with a remaining 0.0065.
