We look at the division of 825012 by 85 
The aim is to understand the frequency of 85 in 825012.

On to step 1:
85 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 85

Let's proceed to step 2:
When dividing 82 by 85, we get 0 with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Grab the next digit (5) from the dividend, add it to 82, then carry on: 825 / 85

Advancing to step 3:
The number 85 fits into 825 9 times, leaving a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 765 from 825 leaves us with 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 85

Moving on to step 4:
When dividing 600 by 85, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtract 595 from 600 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 85

Going ahead to step 5:
The number 85 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 970.0
If we subtract 0 from 51, we get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 85

Moving on to step 6:
512 divided by 85 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 9706.0
The remainder is 2 after subtracting 510 from 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
85 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9706.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 85, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 9706.02
Subtracting 170 from 200 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 85, we get 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 9706.023
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
When dividing 450 by 85, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9706.0235
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
85 goes into 250 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 9706.02352
If we take 170 away from 250, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
If we divide 800 by 85, we get 9 and a remainder of 35.
The next digit of our result is 9. 
Result so far: 9706.023529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 9706.0235294
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
100 divided by 85 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 9706.02352941
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 9706.02352941, and the remainder is 1.5e-08.
