We're dividing 661948 by 2 
We want to figure out the number of times 661948 can be divided by 2.

Moving on to step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Advancing to step 2:
2 goes into 6 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 6 from 6 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Let's proceed to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 330.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

On to step 4:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3309.0
The remainder is 1 after subtracting 18 from 19.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Going ahead to step 5:
14 divided by 2 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 33097.0
Deduct 14 from 14 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

On to 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: 330974.0
Subtract 8 from 8 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.

Moving on to step 7:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 330974.0
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.

Moving 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: 330974.0
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.

Our division results in 330974.0 with a remaining 0.0.
