We look at the division of 8316175 by 815 
The aim is to understand the frequency of 815 in 8316175.

Moving on to step 1:
8 divided by 815 is 0 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.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 815

Step 2:
815 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 815

Advancing to step 3:
If we divide 831 by 815, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 815 from 831 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 815

Moving on to step 4:
If we divide 166 by 815, we get 0 and a remainder of 166.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 166, we get 166.
Bring next digit (1) of the dividend behind the 166 and repeat the process: 1661 / 815

On to step 5:
815 can be fit into 1661 2 times, resulting in a remainder of 31.
The next digit of our result is 2. 
Result so far: 102.0
If we subtract 1630 from 1661, we get 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 815

Advancing to step 6:
The number 815 fits into 317 0 times, leaving a remainder of 317.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
Subtract 0 from 317 to get 317.
Fetch the next digit (5) from the dividend, attach it to 317 and continue: 3175 / 815

Let's proceed to step 7:
When dividing 3175 by 815, we get 3 with a remainder of 730.
Use 3 as the next digit of our solution. 
Result so far: 10203.0
Subtract 2445 from 3175 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 8:
The number 815 fits into 7300 8 times, leaving a remainder of 780.
The number 8 becomes the next digit in our result. 
Result so far: 10203.8
If we subtract 6520 from 7300, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 9:
The number 815 fits into 7800 9 times, leaving a remainder of 465.
Write down 9 as next digit of the result. 
Result so far: 10203.89
Subtracting 7335 from 7800 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 10:
815 can be fit into 4650 5 times, resulting in a remainder of 575.
The next digit of our result is 5. 
Result so far: 10203.895
Deduct 4075 from 4650 and we're left with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 11:
If we divide 5750 by 815, we get 7 and a remainder of 45.
The next digit of our result is 7. 
Result so far: 10203.8957
Deduct 5705 from 5750 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.

Moving on to step 12:
When dividing 450 by 815, we get 0 with a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 10203.8957
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 13:
If we divide 4500 by 815, we get 5 and a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 10203.895705
Subtract 4075 from 4500 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 14:
The number 815 fits into 4250 5 times, leaving a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 10203.8957055
The remainder is 175 after subtracting 4075 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final result is 10203.8957055 with a remainder of 1.75e-06.
