We divide 456424 by 15
The aim is to understand the frequency of 15 in 456424.

Step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 15

Advancing to step 2:
The number 15 fits into 45 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 45 from 45 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 15

Moving on to step 3:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 15

On to step 4:
15 goes into 64 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 304.0
Subtracting 60 from 64 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 15

Step 5:
42 divided by 15 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3042.0
Subtracting 30 from 42 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 15

Step 6:
124 divided by 15 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 30428.0
Subtracting 120 from 124 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 15, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 30428.2
If we subtract 30 from 40, 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.

Moving on to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 30428.26
Deduct 90 from 100 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.

Let's proceed to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 30428.266
Subtracting 90 from 100 leaves us 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 30428.266 with a balance of 0.001.
