We look at the division of 8187298 by 815 
The aim is to understand the frequency of 815 in 8187298.

Moving on to step 1:
The number 815 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 815

Going ahead to step 2:
81 divided by 815 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 815

Step 3:
If we divide 818 by 815, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 815 from 818 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 815

Advancing to step 4:
The number 815 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 37 after subtracting 0 from 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 815

Moving on to step 5:
372 divided by 815 is 0 with a remainder of 372.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 372 leaves us with 372.
Bring next digit (9) of the dividend behind the 372 and repeat the process: 3729 / 815

Moving on to step 6:
The number 815 fits into 3729 4 times, leaving a remainder of 469.
Put 4 as the next digit of the answer. 
Result so far: 1004.0
The remainder is 469 after subtracting 3260 from 3729.
Include the next digit (8) from the dividend after 469, then repeat: 4698 / 815

Going ahead to step 7:
4698 divided by 815 is 5 with a remainder of 623.
Write down 5 as next digit of the result. 
Result so far: 10045.0
If we take 4075 away from 4698, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Going ahead to step 8:
When dividing 6230 by 815, we get 7 with a remainder of 525.
Use 7 as the next digit of our solution. 
Result so far: 10045.7
The remainder is 525 after subtracting 5705 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 9:
5250 divided by 815 is 6 with a remainder of 360.
The next digit of our result is 6. 
Result so far: 10045.76
If we take 4890 away from 5250, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
815 goes into 3600 4 times with a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 10045.764
Subtracting 3260 from 3600 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 11:
When dividing 3400 by 815, we get 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 10045.7644
Subtracting 3260 from 3400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 10045.7644 with a balance of 0.0014.
