We look at the division of 668498 by 2 
Let's see how many times 2 fits into 668498.

Let's proceed to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Going ahead to step 2:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Step 3:
If we divide 8 by 2, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 334.0
Subtract 8 from 8 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Let's proceed to step 4:
When dividing 4 by 2, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3342.0
If we take 4 away from 4, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Advancing to step 5:
When dividing 9 by 2, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 33424.0
Subtract 8 from 9 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Moving on to step 6:
2 can be fit into 18 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 334249.0
If we take 18 away from 18, 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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 334249.0
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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 334249.0
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.

After the division, we end up with 334249.0 and a remainder of 0.0.
