We look at the division of 619130 by 15 
The aim is to understand the frequency of 15 in 619130.

On to 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
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

Let's proceed to step 2:
15 goes into 61 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 60 away from 61, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

Step 3:
If we divide 19 by 15, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 15 from 19 leaves us with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 15

Let's proceed to step 4:
If we divide 41 by 15, we get 2 and a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 412.0
If we take 30 away from 41, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 15

Going ahead to step 5:
If we divide 113 by 15, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 4127.0
The remainder is 8 after subtracting 105 from 113.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Let's proceed to step 6:
When dividing 80 by 15, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 41275.0
If we take 75 away from 80, 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.

Moving on to step 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 41275.3
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.

Step 8:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 41275.33
Subtracting 45 from 50 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.

The final result is 41275.33 with a remainder of 0.005.
