250751 ÷ 85 
The aim is to understand the frequency of 85 in 250751.

Advancing to 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
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 85

Step 2:
25 divided by 85 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 85

Step 3:
85 goes into 250 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 170 from 250 and we're left with 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 85

Step 4:
85 can be fit into 807 9 times, resulting in a remainder of 42.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 765 from 807 and we're left with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 85

Moving on to step 5:
85 goes into 425 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 295.0
Subtract 425 from 425 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 85

Going ahead to step 6:
85 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 2950.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 85 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2950.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
85 goes into 100 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 2950.01
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:
When dividing 150 by 85, we get 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 2950.011
If we take 85 away from 150, we end up 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 2950.011 and a remainder of 0.0065.
