Let's divide 595118 by 15
The aim is to understand the frequency of 15 in 595118.

On to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 15

Advancing to step 2:
59 divided by 15 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
If we take 45 away from 59, we end up with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 15

Moving on to step 3:
15 can be fit into 145 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 135 from 145 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 15

Moving on to step 4:
15 goes into 101 6 times with a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 396.0
Subtracting 90 from 101 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 15

Step 5:
111 divided by 15 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3967.0
If we take 105 away from 111, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 15

Moving on to step 6:
15 goes into 68 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 39674.0
If we subtract 60 from 68, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
15 goes into 80 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 39674.5
Subtracting 75 from 80 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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 39674.53
If we subtract 45 from 50, we 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.

Let's proceed to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 39674.533
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 39674.533 and a remainder of 0.0005.
