We're dividing 302872 by 85 
The aim is to understand the frequency of 85 in 302872.

Step 1:
When dividing 3 by 85, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 85

Step 2:
When dividing 30 by 85, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 85

Step 3:
85 goes into 302 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 47 after subtracting 255 from 302.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 85

Let's proceed to step 4:
478 divided by 85 is 5 with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 425 away from 478, we end up with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 85

Step 5:
When dividing 537 by 85, we get 6 with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
If we subtract 510 from 537, we get 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 85

Advancing to step 6:
If we divide 272 by 85, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3563.0
If we subtract 255 from 272, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
85 goes into 170 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3563.2
If we take 170 away from 170, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 85, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3563.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 85, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3563.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3563.2 and a remainder of 0.0.
