We're dividing 818215 by 2 
Our goal is to divide 818215 by 2.

On to step 1:
8 divided by 2 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Going ahead to step 2:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 1 after subtracting 0 from 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.
Record the quotient 9 as the next digit in the result. 
Result so far: 409.0
If we subtract 18 from 18, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Advancing to step 4:
If we divide 2 by 2, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 4091.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 5:
When dividing 1 by 2, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40910.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Let's proceed to step 6:
2 goes into 15 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 409107.0
If we subtract 14 from 15, we get 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:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 409107.5
If we take 10 away from 10, 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.

On to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 409107.5
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.
Write down 0 as next digit of the result. 
Result so far: 409107.5
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 409107.5 with a balance of 0.0.
