We're dividing 468309 by 15 
Let's see how many times 15 fits into 468309.

Let's proceed to step 1:
15 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 15

Let's proceed to step 2:
15 can be fit into 46 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
If we take 45 away from 46, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Step 3:
The number 15 fits into 18 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 15 away from 18, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 15

Going ahead to step 4:
If we divide 33 by 15, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 312.0
If we subtract 30 from 33, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 15

Advancing to step 5:
The number 15 fits into 30 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 3122.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 15

Going ahead to step 6:
15 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 31220.0
Subtracting 0 from 9 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
15 can be fit into 90 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 31220.6
Subtracting 90 from 90 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31220.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 31220.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 31220.6 and a remainder of 0.0.
