We look at the division of 99508034 by 817 
The aim is to understand the frequency of 817 in 99508034.

Advancing to step 1:
817 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 817

On to step 2:
817 goes into 99 0 times with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 817

Going ahead to step 3:
When dividing 995 by 817, we get 1 with a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 817 from 995 leaves us with 178.
Append the next digit (0) from the dividend to 178 and continue with: 1780 / 817

Let's proceed to step 4:
817 goes into 1780 2 times with a remainder of 146.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1634 from 1780 and we're left with 146.
Fetch the next digit (8) from the dividend, attach it to 146 and continue: 1468 / 817

Moving on to step 5:
If we divide 1468 by 817, we get 1 and a remainder of 651.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we subtract 817 from 1468, we get 651.
Append the next digit (0) from the dividend to 651 and continue with: 6510 / 817

Advancing to step 6:
If we divide 6510 by 817, we get 7 and a remainder of 791.
The next digit of our result is 7. 
Result so far: 1217.0
If we subtract 5719 from 6510, we get 791.
Include the next digit (3) from the dividend after 791, then repeat: 7913 / 817

Advancing to step 7:
817 goes into 7913 9 times with a remainder of 560.
The number 9 becomes the next digit in our result. 
Result so far: 12179.0
If we take 7353 away from 7913, we end up with 560.
Include the next digit (4) from the dividend after 560, then repeat: 5604 / 817

Let's proceed to step 8:
817 goes into 5604 6 times with a remainder of 702.
Use 6 as the next digit of our solution. 
Result so far: 121796.0
If we subtract 4902 from 5604, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Let's proceed to step 9:
817 goes into 7020 8 times with a remainder of 484.
Use 8 as the next digit of our solution. 
Result so far: 121796.8
If we take 6536 away from 7020, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 10:
The number 817 fits into 4840 5 times, leaving a remainder of 755.
Use 5 as the next digit of our solution. 
Result so far: 121796.85
The remainder is 755 after subtracting 4085 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Let's proceed to step 11:
7550 divided by 817 is 9 with a remainder of 197.
The number 9 becomes the next digit in our result. 
Result so far: 121796.859
Deduct 7353 from 7550 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 12:
If we divide 1970 by 817, we get 2 and a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 121796.8592
If we subtract 1634 from 1970, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 13:
The number 817 fits into 3360 4 times, leaving a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 121796.85924
If we subtract 3268 from 3360, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 14:
920 divided by 817 is 1 with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 121796.859241
The remainder is 103 after subtracting 817 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 15:
817 can be fit into 1030 1 times, resulting in a remainder of 213.
Write down 1 as next digit of the result. 
Result so far: 121796.8592411
Deduct 817 from 1030 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

In conclusion, the division gives 121796.8592411 with a balance of 2.13e-06.
