We look at the division of 398994 by 2 
Our goal is to divide 398994 by 2.

Step 1:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 2 from 3 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Advancing to step 2:
19 divided by 2 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 18 from 19 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Moving on to step 3:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Subtracting 18 from 18 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Step 4:
If we divide 9 by 2, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 1994.0
The remainder is 1 after subtracting 8 from 9.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Let's proceed to step 5:
19 divided by 2 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19949.0
If we take 18 away from 19, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Moving on to step 6:
When dividing 14 by 2, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 199497.0
If we subtract 14 from 14, 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.

On to step 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 199497.0
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 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 199497.0
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.

The final result is 199497.0 with a remainder of 0.0.
