800404 divided by 16 
We're looking to find how many times 16 goes into 800404.

Step 1:
8 divided by 16 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 16

Let's proceed to step 2:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 80 from 80 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 16

Moving on to step 3:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 16

Advancing to step 4:
16 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 500.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 16

Advancing to step 5:
16 goes into 40 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5002.0
If we subtract 32 from 40, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 16

Step 6:
16 can be fit into 84 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 50025.0
Deduct 80 from 84 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 16, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 50025.2
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.

Let's proceed to step 8:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 50025.25
Subtracting 80 from 80 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.

Advancing to step 9:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50025.25
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.

Step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 50025.25
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.

In conclusion, the division gives 50025.25 with a balance of 0.0.
