486449 divided by 15 
Our goal is to divide 486449 by 15.

Advancing to 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.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 15

Step 2:
48 divided by 15 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 45 from 48 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 15

Advancing to step 3:
If we divide 36 by 15, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
The remainder is 6 after subtracting 30 from 36.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 15

Let's proceed to step 4:
The number 15 fits into 64 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
The remainder is 4 after subtracting 60 from 64.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 15

Moving on to step 5:
15 can be fit into 44 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 3242.0
Subtract 30 from 44 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 15

Let's proceed to step 6:
When dividing 149 by 15, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 32429.0
Subtract 135 from 149 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.

Let's proceed to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 32429.9
Deduct 135 from 140 and we're left 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 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 32429.93
Deduct 45 from 50 and we're left 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.

On to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 32429.933
Subtracting 45 from 50 leaves us 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 32429.933 with a remaining 0.0005.
