We're dividing 450489 by 15 
Our goal is to divide 450489 by 15.

Step 1:
When dividing 4 by 15, we get 0 with 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.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 15

Advancing to step 2:
The number 15 fits into 45 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 45 from 45 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 15

Let's proceed to step 3:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 0, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 15

Moving on to step 4:
If we divide 4 by 15, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 300.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 15

Step 5:
If we divide 48 by 15, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3003.0
Deduct 45 from 48 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 15

Step 6:
When dividing 39 by 15, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 30032.0
If we subtract 30 from 39, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 15 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 30032.6
If we take 90 away from 90, 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.

On to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30032.6
If we subtract 0 from 0, we get 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 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30032.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 30032.6 with a balance of 0.0.
