623356 ÷ 2 
Let's see how many times 2 fits into 623356.

Step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Let's proceed to step 2:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Going ahead to step 3:
3 divided by 2 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 311.0
If we take 2 away from 3, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Advancing to step 4:
The number 2 fits into 13 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 3116.0
Subtracting 12 from 13 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

On to step 5:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 31167.0
The remainder is 1 after subtracting 14 from 15.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Let's proceed to step 6:
The number 2 fits into 16 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 311678.0
The remainder is 0 after subtracting 16 from 16.
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 7:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 311678.0
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.

Moving on to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 311678.0
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.

In conclusion, the division gives 311678.0 with a balance of 0.0.
