We look at the division of 855416 by 15 
The aim is to understand the frequency of 15 in 855416.

Going ahead to step 1:
15 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 15

Step 2:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 75 from 85, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 15

Let's proceed to step 3:
15 goes into 105 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we subtract 105 from 105, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

On to step 4:
4 divided by 15 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 570.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 15

Advancing to step 5:
41 divided by 15 is 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 5702.0
Deduct 30 from 41 and we're left with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 15

Moving on to step 6:
15 goes into 116 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 57027.0
If we take 105 away from 116, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 15, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 57027.7
Subtract 105 from 110 to 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.

Moving on to step 8:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 57027.73
If we take 45 away from 50, we end up 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.

On to step 9:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 57027.733
If we take 45 away from 50, we end up 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.

In conclusion, the division gives 57027.733 with a balance of 0.0005.
