We're dividing 729240 by 3 
Let's see how many times 3 fits into 729240.

Advancing to step 1:
7 divided by 3 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 3

Let's proceed to step 2:
12 divided by 3 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 0 after subtracting 12 from 12.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

On to step 3:
If we divide 9 by 3, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
If we subtract 9 from 9, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Going ahead to step 4:
When dividing 2 by 3, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 2430.0
If we subtract 0 from 2, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

On to step 5:
3 goes into 24 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 24308.0
Subtract 24 from 24 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

On to step 6:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 243080.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 243080.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 243080.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 243080.0, and the remainder is 0.0.
