818358 ÷ 2 
Our goal is to divide 818358 by 2.

Step 1:
If we divide 8 by 2, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Moving on to step 2:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

On to step 3:
18 divided by 2 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 409.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Advancing to step 4:
3 divided by 2 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4091.0
Subtract 2 from 3 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Advancing to step 5:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 40917.0
If we subtract 14 from 15, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 6:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 409179.0
Deduct 18 from 18 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.

On to step 7:
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: 409179.0
Subtract 0 from 0 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.
Write down 0 as next digit of the result. 
Result so far: 409179.0
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.

After the division, we end up with 409179.0 and a remainder of 0.0.
