We divide 438512 by 15
The aim is to understand the frequency of 15 in 438512.

Step 1:
15 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 15

Moving on to step 2:
The number 15 fits into 43 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 30 from 43 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 15

Advancing to step 3:
15 can be fit into 138 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 135 from 138 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 15

Moving on to step 4:
15 can be fit into 35 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
The remainder is 5 after subtracting 30 from 35.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 15

Advancing to step 5:
15 goes into 51 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 2923.0
If we subtract 45 from 51, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 15

Let's proceed to step 6:
15 goes into 62 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 29234.0
The remainder is 2 after subtracting 60 from 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 29234.1
If we subtract 15 from 20, 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.

On to step 8:
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: 29234.13
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.

Step 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 29234.133
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.

In conclusion, the division gives 29234.133 with a balance of 0.0005.
