We divide 986891 by 2
We're looking to find how many times 2 goes into 986891.

Going ahead to step 1:
If we divide 9 by 2, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 8 from 9, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Step 2:
2 goes into 18 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Advancing to step 3:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 493.0
Subtract 6 from 6 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Step 4:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4934.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Step 5:
If we divide 9 by 2, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 49344.0
Subtract 8 from 9 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Moving on to step 6:
When dividing 11 by 2, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 493445.0
The remainder is 1 after subtracting 10 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
2 goes into 10 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 493445.5
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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 493445.5
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.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 493445.5
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.

After the division, we end up with 493445.5 and a remainder of 0.0.
