We divide 814209 by 1
Let's see how many times 1 fits into 814209.

Step 1:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 1 away from 1, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

On to step 3:
If we divide 4 by 1, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 4:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 8142.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 5:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 81420.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 6:
9 divided by 1 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 814209.0
Subtracting 9 from 9 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.

Step 7:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 814209.0
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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 814209.0
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.

After the division, we end up with 814209.0 and a remainder of 0.0.
