838980 ÷ 2 
We want to divide 838980 by 2.

Going ahead to step 1:
2 goes into 8 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Moving on to step 2:
When dividing 3 by 2, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 2 from 3 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Going ahead to step 3:
18 divided by 2 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

On to step 4:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4194.0
If we take 8 away from 9, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Step 5:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 41949.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Advancing to step 6:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 419490.0
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 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 419490.0
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.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 419490.0
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.

The final outcome is 419490.0, with a leftover of 0.0.
