We divide 728311 by 30
We want to figure out the number of times 728311 can be divided by 30.

Moving on to step 1:
7 divided by 30 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 30

On to step 2:
If we divide 72 by 30, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 72 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 30

On to step 3:
30 goes into 128 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 120 away from 128, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 30

Step 4:
30 goes into 83 2 times with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 242.0
If we take 60 away from 83, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 30

Step 5:
30 can be fit into 231 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 2427.0
The remainder is 21 after subtracting 210 from 231.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 30

Let's proceed to step 6:
If we divide 211 by 30, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 24277.0
If we subtract 210 from 211, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 24277.0
If we take 0 away from 10, 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.

On to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 24277.03
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.

Moving on to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 24277.033
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.

The final result is 24277.033 with a remainder of 0.001.
