Let's divide 404509 by 16
We want to divide 404509 by 16.

Advancing to step 1:
If we divide 4 by 16, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 16

Step 2:
If we divide 40 by 16, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 32 from 40 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 16

Moving on to step 3:
84 divided by 16 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 80 from 84 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 16

Step 4:
45 divided by 16 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 252.0
Subtracting 32 from 45 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 16

On to step 5:
If we divide 130 by 16, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 2528.0
Subtracting 128 from 130 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 16

Advancing to step 6:
If we divide 29 by 16, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 25281.0
If we subtract 16 from 29, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
16 can be fit into 130 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 25281.8
Subtract 128 from 130 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
16 can be fit into 20 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 25281.81
If we take 16 away from 20, we end up 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.

Moving on to step 9:
40 divided by 16 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 25281.812
If we subtract 32 from 40, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25281.8125
Subtract 80 from 80 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 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25281.8125
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.

On to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25281.8125
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.

In conclusion, the division gives 25281.8125 with a balance of 0.0.
