We look at the division of 661929 by 2 
We want to figure out the number of times 661929 can be divided by 2.

On to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Going ahead to step 2:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Let's proceed to step 3:
1 divided by 2 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 330.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Advancing to step 4:
When dividing 19 by 2, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3309.0
Deduct 18 from 19 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Advancing to step 5:
If we divide 12 by 2, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 33096.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Advancing to step 6:
9 divided by 2 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 330964.0
Deduct 8 from 9 and we're left 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.

Moving on to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 330964.5
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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 330964.5
Subtracting 0 from 0 leaves us 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.

Step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 330964.5
Subtract 0 from 0 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.

The quotient of the division is 330964.5, and the remainder is 0.0.
