We look at the division of 504895 by 15 
The aim is to understand the frequency of 15 in 504895.

Moving on to step 1:
15 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 15

Advancing to step 2:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 5 after subtracting 45 from 50.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 15

Going ahead to step 3:
15 can be fit into 54 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 45 from 54 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 15

On to step 4:
When dividing 98 by 15, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 336.0
The remainder is 8 after subtracting 90 from 98.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 15

Moving on to step 5:
15 goes into 89 5 times with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 3365.0
If we take 75 away from 89, we end up with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 15

On to step 6:
When dividing 145 by 15, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 33659.0
Deduct 135 from 145 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.

Going ahead to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 33659.6
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.

Advancing to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 33659.66
Subtract 90 from 100 to 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.

Our division results in 33659.66 with a remaining 0.01.
