We look at the division of 689623 by 2 
Let's see how many times 2 fits into 689623.

Going ahead to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 6 from 6, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

On to step 2:
When dividing 8 by 2, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 8 away from 8, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

On to step 3:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 2

Let's proceed to step 4:
2 goes into 16 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 3448.0
If we subtract 16 from 16, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

On to step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 34481.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Advancing to step 6:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 344811.0
Subtracting 2 from 3 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.

Step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 344811.5
If we subtract 10 from 10, 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.

Step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 344811.5
Deduct 0 from 0 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 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 344811.5
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.

In conclusion, the division gives 344811.5 with a balance of 0.0.
