989491 ÷ 2 
We want to divide 989491 by 2.

Going ahead to step 1:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Step 2:
When dividing 18 by 2, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 18 from 18 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Step 3:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 494.0
Subtract 8 from 9 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

On to step 4:
The number 2 fits into 14 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 4947.0
Subtract 14 from 14 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Step 5:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 49474.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Step 6:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 494745.0
If we subtract 10 from 11, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 494745.5
If we subtract 10 from 10, 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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 494745.5
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.

Advancing to step 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 494745.5
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.

In conclusion, the division gives 494745.5 with a balance of 0.0.
