We divide 779661 by 2
We want to figure out the number of times 779661 can be divided by 2.

Advancing to step 1:
2 goes into 7 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Let's proceed to step 2:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 16 from 17 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Advancing to step 3:
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: 389.0
Subtracting 18 from 19 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Advancing to step 4:
If we divide 16 by 2, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 3898.0
Subtract 16 from 16 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 38983.0
If we subtract 6 from 6, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Moving on to step 6:
If we divide 1 by 2, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 389830.0
If we subtract 0 from 1, we get 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:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 389830.5
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.

Advancing to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 389830.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 389830.5
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.

The final outcome is 389830.5, with a leftover of 0.0.
