399828 ÷ 2 
Our goal is to divide 399828 by 2.

Moving on to step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Step 2:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 1 after subtracting 18 from 19.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Moving on to step 3:
2 goes into 19 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 199.0
If we take 18 away from 19, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Step 4:
18 divided by 2 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 1999.0
Subtract 18 from 18 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

On to step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 19991.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Moving on to step 6:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 199914.0
The remainder is 0 after subtracting 8 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 199914.0
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.

On to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 199914.0
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.

Our division results in 199914.0 with a remaining 0.0.
