324494 ÷ 15 
The aim is to understand the frequency of 15 in 324494.

Step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 15

Let's proceed to step 2:
32 divided by 15 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 30 from 32.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 15

Advancing to step 3:
If we divide 24 by 15, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 15 from 24, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 15

On to step 4:
15 can be fit into 94 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Subtracting 90 from 94 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

On to step 5:
If we divide 49 by 15, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 2163.0
If we subtract 45 from 49, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 15

Advancing to step 6:
When dividing 44 by 15, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 21632.0
Subtract 30 from 44 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 21632.9
If we subtract 135 from 140, 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.

Advancing to step 8:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 21632.93
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.

Moving on to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 21632.933
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.

Our division results in 21632.933 with a remaining 0.0005.
