Let's divide 910491 by 2
Let's see how many times 2 fits into 910491.

On to step 1:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Moving on to step 2:
When dividing 11 by 2, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 10 from 11 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Going ahead to step 3:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 455.0
Subtracting 10 from 10 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

On to step 4:
When dividing 4 by 2, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 4552.0
Subtract 4 from 4 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Step 5:
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: 45524.0
Subtracting 8 from 9 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

On to step 6:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 455245.0
Subtracting 10 from 11 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 455245.5
Deduct 10 from 10 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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 455245.5
The remainder is 0 after subtracting 0 from 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 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 455245.5
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.

After the division, we end up with 455245.5 and a remainder of 0.0.
