We look at the division of 814438 by 2 
We're looking to find how many times 2 goes into 814438.

Going ahead to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Moving on to step 2:
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: 40.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 2

Advancing to step 3:
If we divide 14 by 2, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 407.0
Subtract 14 from 14 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

On to step 4:
If we divide 4 by 2, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4072.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Moving on to step 5:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 40721.0
If we subtract 2 from 3, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Advancing to step 6:
2 goes into 18 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 407219.0
If we subtract 18 from 18, 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.

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 407219.0
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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 407219.0
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.

The quotient of the division is 407219.0, and the remainder is 0.0.
