We're dividing 781781 by 2 
We want to figure out the number of times 781781 can be divided by 2.

Step 1:
2 goes into 7 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 6 from 7 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Advancing to step 2:
When dividing 18 by 2, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 18 from 18 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Going ahead to step 4:
If we divide 17 by 2, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 3908.0
Subtract 16 from 17 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Let's proceed to step 5:
2 goes into 18 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39089.0
Subtract 18 from 18 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Let's proceed to step 6:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 390890.0
If we take 0 away from 1, we end up 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.

On to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 390890.5
Subtracting 10 from 10 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.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 390890.5
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.

Moving on to step 9:
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: 390890.5
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.

The final result is 390890.5 with a remainder of 0.0.
