We divide 804209 by 1
Let's see how many times 1 fits into 804209.

On to step 1:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Advancing to step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 3:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Advancing to step 4:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 8042.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 5:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80420.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Let's proceed to step 6:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 804209.0
Subtract 9 from 9 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.

Moving on to step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 804209.0
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.

Step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 804209.0
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.

The final outcome is 804209.0, with a leftover of 0.0.
