We're dividing 409803 by 16 
We want to divide 409803 by 16.

Going ahead to step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 16

Step 2:
40 divided by 16 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 32 from 40, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 16

Let's proceed to step 3:
16 can be fit into 89 5 times, resulting in a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 80 from 89 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 16

Let's proceed to step 4:
16 can be fit into 98 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 256.0
If we take 96 away from 98, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 16

Advancing to step 5:
When dividing 20 by 16, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 2561.0
The remainder is 4 after subtracting 16 from 20.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 16

Step 6:
When dividing 43 by 16, we get 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 25612.0
Subtracting 32 from 43 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 16, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 25612.6
The remainder is 14 after subtracting 96 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 16 fits into 140 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 25612.68
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
16 goes into 120 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 25612.687
The remainder is 8 after subtracting 112 from 120.
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 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 25612.6875
Deduct 80 from 80 and we're left 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:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25612.6875
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.

Step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25612.6875
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.

In conclusion, the division gives 25612.6875 with a balance of 0.0.
