723149 ÷ 15 
We want to divide 723149 by 15.

Going ahead to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 15

Advancing to step 2:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 60 from 72 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 15

Let's proceed to step 3:
When dividing 123 by 15, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 3 after subtracting 120 from 123.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

On to step 4:
31 divided by 15 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 482.0
If we subtract 30 from 31, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 15

Step 5:
15 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 4820.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 15

Step 6:
15 can be fit into 149 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 48209.0
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.

Moving on to step 7:
When dividing 140 by 15, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 48209.9
If we subtract 135 from 140, we 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 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 48209.93
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.

Step 9:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 48209.933
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.

The final result is 48209.933 with a remainder of 0.0005.
