449743 divided by 15 
We want to figure out the number of times 449743 can be divided by 15.

Step 1:
4 divided by 15 is 0 with 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 (4) of the dividend behind the 4 and repeat the process: 44 / 15

Step 2:
15 can be fit into 44 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 30 from 44 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 15

Advancing to step 3:
The number 15 fits into 149 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 135 from 149 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 15

Let's proceed to step 4:
15 goes into 147 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 299.0
If we take 135 away from 147, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 15

Advancing to step 5:
The number 15 fits into 124 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 2998.0
Subtract 120 from 124 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 15

Let's proceed to step 6:
The number 15 fits into 43 2 times, leaving a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 29982.0
Subtract 30 from 43 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.

Let's proceed to step 7:
15 can be fit into 130 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 29982.8
If we take 120 away from 130, 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.

Moving on to step 8:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 29982.86
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
15 goes into 100 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 29982.866
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.

In conclusion, the division gives 29982.866 with a balance of 0.001.
