We look at the division of 276799 by 85 
The aim is to understand the frequency of 85 in 276799.

On to step 1:
When dividing 2 by 85, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 85

Let's proceed to step 2:
85 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 85

Moving on to step 3:
The number 85 fits into 276 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 255 from 276 to get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 85

Moving on to step 4:
85 can be fit into 217 2 times, resulting in a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 170 from 217, we get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 85

Going ahead to step 5:
The number 85 fits into 479 5 times, leaving a remainder of 54.
The next digit of our result is 5. 
Result so far: 325.0
Subtract 425 from 479 to get 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 85

On to step 6:
85 can be fit into 549 6 times, resulting in a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 3256.0
If we take 510 away from 549, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
85 can be fit into 390 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 3256.4
Deduct 340 from 390 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 3256.45
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
750 divided by 85 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 3256.458
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
700 divided by 85 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 3256.4588
Subtracting 680 from 700 leaves us 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.

The final result is 3256.4588 with a remainder of 0.0002.
