Let's divide 448273 by 15
We're looking to find how many times 15 goes into 448273.

Step 1:
15 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 15

Going ahead to step 2:
44 divided by 15 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 30 from 44 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 15

Moving on to step 3:
148 divided by 15 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 135 from 148 leaves us with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 15

Advancing to step 4:
The number 15 fits into 132 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 298.0
If we subtract 120 from 132, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 15

Advancing to step 5:
15 can be fit into 127 8 times, resulting in a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 2988.0
Subtract 120 from 127 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 15

Moving on to step 6:
73 divided by 15 is 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 29884.0
Subtract 60 from 73 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 15 fits into 130 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 29884.8
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 29884.86
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 29884.866
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 29884.866, and the remainder is 0.001.
