Let's divide 717649 by 2
We're looking to find how many times 2 goes into 717649.

Going ahead to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Moving on to step 2:
2 goes into 11 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 10 from 11 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Going ahead to step 3:
2 can be fit into 17 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 358.0
If we take 16 away from 17, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Advancing to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 3588.0
If we subtract 16 from 16, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Going ahead to step 5:
When dividing 4 by 2, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 35882.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Let's proceed to step 6:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 358824.0
Subtracting 8 from 9 leaves us 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:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 358824.5
Deduct 10 from 10 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.

Advancing to step 8:
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: 358824.5
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.

Going ahead to step 9:
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: 358824.5
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 358824.5, with a leftover of 0.0.
