We divide 728430 by 3
Let's see how many times 3 fits into 728430.

Moving on to step 1:
When dividing 7 by 3, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 6 from 7 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Advancing to step 2:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 12 from 12 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Going ahead to step 3:
If we divide 8 by 3, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 242.0
Deduct 6 from 8 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Step 4:
If we divide 24 by 3, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2428.0
If we subtract 24 from 24, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

On to step 5:
If we divide 3 by 3, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 24281.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Let's proceed 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: 242810.0
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.

Step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 242810.0
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.

Let's proceed to step 8:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 242810.0
Subtracting 0 from 0 leaves us 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 final outcome is 242810.0, with a leftover of 0.0.
