We divide 816438 by 3
Our goal is to divide 816438 by 3.

Going ahead to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

On to step 2:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 21 from 21, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Advancing to step 3:
When dividing 6 by 3, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Step 4:
When dividing 4 by 3, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 2721.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Moving on to step 5:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 27214.0
Deduct 12 from 13 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Going ahead to step 6:
3 goes into 18 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 272146.0
Deduct 18 from 18 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.

Moving on to step 7:
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: 272146.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 272146.0
If we subtract 0 from 0, we 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.

After the division, we end up with 272146.0 and a remainder of 0.0.
