We look at the division of 614593 by 15 
The aim is to understand the frequency of 15 in 614593.

Step 1:
15 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 15

Going ahead to step 2:
When dividing 61 by 15, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 60 from 61 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 15

Going ahead to step 3:
14 divided by 15 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 14, we get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 15

Step 4:
If we divide 145 by 15, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 409.0
If we subtract 135 from 145, we get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 15

On to step 5:
The number 15 fits into 109 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4097.0
Subtract 105 from 109 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 15

Let's proceed to step 6:
If we divide 43 by 15, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 40972.0
Subtract 30 from 43 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 15, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 40972.8
If we take 120 away from 130, 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.

Advancing to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 40972.86
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.

Going ahead to step 9:
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: 40972.866
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.

In conclusion, the division gives 40972.866 with a balance of 0.001.
