Let's divide 8498 by 15
The aim is to understand the frequency of 15 in 8498.

Step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 15

Advancing to step 2:
When dividing 84 by 15, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 9 after subtracting 75 from 84.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 15

Moving on to step 3:
15 can be fit into 99 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we take 90 away from 99, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 15

Let's proceed to step 4:
The number 15 fits into 98 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 566.0
Deduct 90 from 98 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 5:
80 divided by 15 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 566.5
Subtracting 75 from 80 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 566.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 566.533
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 566.533 and a remainder of 0.0005.
