482807 divided by 15 
The aim is to understand the frequency of 15 in 482807.

Advancing to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 15

Step 2:
If we divide 48 by 15, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 45 from 48 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 15

Advancing to step 3:
32 divided by 15 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 30 from 32 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 15

Let's proceed to step 4:
15 goes into 28 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtract 15 from 28 to get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 15

Moving on to step 5:
15 goes into 130 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 3218.0
Subtracting 120 from 130 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 15

Step 6:
107 divided by 15 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 32187.0
Subtracting 105 from 107 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 32187.1
If we take 15 away from 20, 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.

Let's proceed to step 8:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 32187.13
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.

Advancing to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 32187.133
Subtract 45 from 50 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.

The quotient of the division is 32187.133, and the remainder is 0.0005.
