We divide 720449 by 15
We're looking to find how many times 15 goes into 720449.

On to step 1:
7 divided by 15 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 15

Going ahead to step 2:
If we divide 72 by 15, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 12 after subtracting 60 from 72.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

On to step 3:
When dividing 120 by 15, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 120 from 120 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

Step 4:
15 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 15

Moving on to step 5:
When dividing 44 by 15, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 4802.0
Subtract 30 from 44 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 15

On to step 6:
If we divide 149 by 15, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 48029.0
Deduct 135 from 149 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 48029.9
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 48029.93
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 48029.933
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 48029.933 with a remaining 0.0005.
