We look at the division of 15204159 by 323 
We want to figure out the number of times 15204159 can be divided by 323.

Going ahead to step 1:
The number 323 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 323

On to step 2:
When dividing 15 by 323, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 323

Let's proceed to step 3:
The number 323 fits into 152 0 times, leaving a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 152 and we're left with 152.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 323

Step 4:
323 can be fit into 1520 4 times, resulting in a remainder of 228.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1292 from 1520, we get 228.
Take the next digit (4) from the dividend and append it to 228, then repeat: 2284 / 323

Moving on to step 5:
If we divide 2284 by 323, we get 7 and a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 2261 from 2284, we get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 323

Advancing to step 6:
323 can be fit into 231 0 times, resulting in a remainder of 231.
Put 0 as the next digit of the answer. 
Result so far: 470.0
Subtract 0 from 231 to get 231.
Include the next digit (5) from the dividend after 231, then repeat: 2315 / 323

Moving on to step 7:
When dividing 2315 by 323, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 4707.0
Subtracting 2261 from 2315 leaves us with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 323

Going ahead to step 8:
The number 323 fits into 549 1 times, leaving a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 47071.0
Subtract 323 from 549 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 9:
If we divide 2260 by 323, we get 6 and a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 47071.6
Subtract 1938 from 2260 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 10:
When dividing 3220 by 323, we get 9 with a remainder of 313.
Record the quotient 9 as the next digit in the result. 
Result so far: 47071.69
If we subtract 2907 from 3220, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 11:
323 can be fit into 3130 9 times, resulting in a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 47071.699
If we take 2907 away from 3130, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

In conclusion, the division gives 47071.699 with a balance of 0.0223.
