We divide 818992 by 15
The aim is to understand the frequency of 15 in 818992.

Moving on to step 1:
8 divided by 15 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 15

On to step 2:
The number 15 fits into 81 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 75 away from 81, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 15

Step 3:
15 can be fit into 68 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 60 from 68, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 15

Going ahead to step 4:
The number 15 fits into 89 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 545.0
If we take 75 away from 89, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 15

On to step 5:
If we divide 149 by 15, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 5459.0
Deduct 135 from 149 and we're left with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 15

Going ahead to step 6:
142 divided by 15 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 54599.0
Subtract 135 from 142 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 54599.4
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.

On to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 54599.46
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.

Going ahead to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 54599.466
If we subtract 90 from 100, we get 10.
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 54599.466 with a balance of 0.001.
