Let's divide 830347 by 15
The aim is to understand the frequency of 15 in 830347.

Advancing to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 15

Let's proceed to step 2:
If we divide 83 by 15, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 8 after subtracting 75 from 83.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 15

Moving on to step 3:
If we divide 80 by 15, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtracting 75 from 80 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 15

Step 4:
15 goes into 53 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 553.0
Deduct 45 from 53 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 15

Step 5:
The number 15 fits into 84 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5535.0
If we take 75 away from 84, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 15

Moving on to step 6:
The number 15 fits into 97 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 55356.0
Subtracting 90 from 97 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
15 can be fit into 70 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 55356.4
Deduct 60 from 70 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.

Step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 55356.46
If we take 90 away from 100, we end up 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.

Let's proceed to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 55356.466
Deduct 90 from 100 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.

The final result is 55356.466 with a remainder of 0.001.
