We divide 839451 by 3
Our goal is to divide 839451 by 3.

Moving on to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Let's proceed to step 2:
3 goes into 23 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

Moving on to step 3:
If we divide 29 by 3, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 279.0
If we subtract 27 from 29, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

On to step 4:
When dividing 24 by 3, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2798.0
Subtract 24 from 24 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

On to step 5:
When dividing 5 by 3, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 27981.0
Subtracting 3 from 5 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Moving on to step 6:
3 goes into 21 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 279817.0
Subtract 21 from 21 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.
Put 0 as the next digit of the answer. 
Result so far: 279817.0
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.

Going ahead to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 279817.0
The remainder is 0 after subtracting 0 from 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 result is 279817.0 with a remainder of 0.0.
