804209 ÷ 16 
Our goal is to divide 804209 by 16.

Advancing to step 1:
8 divided by 16 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 16

Step 2:
80 divided by 16 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 80 from 80 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 16

Going ahead to step 3:
4 divided by 16 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 16

Step 4:
16 goes into 42 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 502.0
Subtract 32 from 42 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 16

Moving on to step 5:
If we divide 100 by 16, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5026.0
The remainder is 4 after subtracting 96 from 100.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 16

Moving on to step 6:
49 divided by 16 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 50263.0
If we take 48 away from 49, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 16 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 50263.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
16 can be fit into 100 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 50263.06
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 50263.062
Deduct 32 from 40 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 50263.0625
If we take 80 away from 80, 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 11:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50263.0625
The remainder is 0 after subtracting 0 from 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 12:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50263.0625
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.

The final result is 50263.0625 with a remainder of 0.0.
