684459 divided by 2 
We're looking to find how many times 2 goes into 684459.

Step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

On to step 2:
2 goes into 8 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 8 from 8 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Moving on to step 3:
4 divided by 2 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 342.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Advancing to step 4:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3422.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Step 5:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 34222.0
Subtract 4 from 5 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Advancing to step 6:
If we divide 19 by 2, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 342229.0
Deduct 18 from 19 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.

Let's proceed to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 342229.5
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 342229.5
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.

Going ahead to step 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 342229.5
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.

In conclusion, the division gives 342229.5 with a balance of 0.0.
