728575 ÷ 18 
Let's see how many times 18 fits into 728575.

Step 1:
The number 18 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 18

Let's proceed to step 2:
The number 18 fits into 72 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 72 from 72 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 18

Going ahead to step 3:
18 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 18

Going ahead to step 4:
The number 18 fits into 85 4 times, leaving a remainder of 13.
The next digit of our result is 4. 
Result so far: 404.0
If we subtract 72 from 85, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 18

Moving on to step 5:
If we divide 137 by 18, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 4047.0
If we subtract 126 from 137, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 18

Let's proceed to step 6:
18 goes into 115 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 40476.0
If we subtract 108 from 115, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 18, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 40476.3
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
18 goes into 160 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 40476.38
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 18, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 40476.388
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 40476.388 with a balance of 0.0016.
