448782 ÷ 15 
We want to figure out the number of times 448782 can be divided by 15.

On to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 15

Advancing to step 2:
15 can be fit into 44 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 30 from 44 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 15

Moving on to step 3:
15 can be fit into 148 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 135 from 148 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 15

Step 4:
137 divided by 15 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
Deduct 135 from 137 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 15

Step 5:
The number 15 fits into 28 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 2991.0
Subtract 15 from 28 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 15

Going ahead to step 6:
132 divided by 15 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 29918.0
If we take 120 away from 132, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 29918.8
Deduct 120 from 120 and we're left 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.

Moving on to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29918.8
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.

Let's proceed to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29918.8
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.

The final result is 29918.8 with a remainder of 0.0.
