669728 divided by 2 
Let's see how many times 2 fits into 669728.

Going ahead to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

On to step 2:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Moving on to step 3:
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: 334.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Let's proceed to step 4:
When dividing 17 by 2, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 3348.0
Subtract 16 from 17 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Advancing to step 5:
2 can be fit into 12 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 33486.0
If we take 12 away from 12, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Step 6:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 334864.0
Deduct 8 from 8 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 7:
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: 334864.0
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.

On to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 334864.0
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.

Our division results in 334864.0 with a remaining 0.0.
