We're dividing 668899 by 2 
Our goal is to divide 668899 by 2.

Advancing to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Let's proceed to step 2:
6 divided by 2 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 3:
8 divided by 2 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 334.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Step 4:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 3344.0
If we subtract 8 from 8, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Advancing to step 5:
9 divided by 2 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 33444.0
Deduct 8 from 9 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Moving on to step 6:
If we divide 19 by 2, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 334449.0
Subtracting 18 from 19 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:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 334449.5
Subtract 10 from 10 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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 334449.5
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.

Let's proceed 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: 334449.5
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.

The final result is 334449.5 with a remainder of 0.0.
