Let's divide 812440 by 2
We want to divide 812440 by 2.

Going ahead to step 1:
2 goes into 8 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

On to step 2:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Going ahead to step 3:
The number 2 fits into 12 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
If we take 12 away from 12, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Let's proceed to step 4:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 4062.0
Subtract 4 from 4 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Going ahead to step 5:
When dividing 4 by 2, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 40622.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

On to step 6:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 406220.0
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.

Moving on to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 406220.0
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.

Step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 406220.0
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.

After the division, we end up with 406220.0 and a remainder of 0.0.
