We look at the division of 997636 by 85 
The aim is to understand the frequency of 85 in 997636.

Let's proceed to step 1:
85 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 85

Moving on to step 2:
The number 85 fits into 99 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 85 from 99 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 85

On to step 3:
85 can be fit into 147 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 62 after subtracting 85 from 147.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 85

Step 4:
85 can be fit into 626 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 595 from 626 and we're left with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 85

Moving on to step 5:
The number 85 fits into 313 3 times, leaving a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 1173.0
If we take 255 away from 313, we end up with 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 85

Moving on to step 6:
When dividing 586 by 85, we get 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 11736.0
Subtracting 510 from 586 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
760 divided by 85 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 11736.8
If we take 680 away from 760, 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 8:
The number 85 fits into 800 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 11736.89
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
350 divided by 85 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 11736.894
Deduct 340 from 350 and we're left 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.

Going ahead to step 10:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11736.8941
Subtract 85 from 100 to 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.

Step 11:
85 goes into 150 1 times with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11736.89411
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.

The final result is 11736.89411 with a remainder of 6.5e-05.
