828304 divided by 15 
The aim is to understand the frequency of 15 in 828304.

Advancing to step 1:
8 divided by 15 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 15

Let's proceed to step 2:
The number 15 fits into 82 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 7 after subtracting 75 from 82.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 15

Moving on to step 3:
When dividing 78 by 15, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 3 after subtracting 75 from 78.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 15

On to step 4:
The number 15 fits into 33 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 552.0
The remainder is 3 after subtracting 30 from 33.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 15

Going ahead to step 5:
The number 15 fits into 30 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 5522.0
If we subtract 30 from 30, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 15

Step 6:
When dividing 4 by 15, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 55220.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 15, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 55220.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 55220.26
Subtracting 90 from 100 leaves us 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.

Step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 55220.266
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 55220.266 with a balance of 0.001.
