We're dividing 408255 by 16 
We want to divide 408255 by 16.

Let's proceed to step 1:
If we divide 4 by 16, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 16

Let's proceed to step 2:
16 can be fit into 40 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 32 from 40 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 16

Step 3:
88 divided by 16 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 80 from 88 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 16

Let's proceed to step 4:
The number 16 fits into 82 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Deduct 80 from 82 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 16

Let's proceed to step 5:
The number 16 fits into 25 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 2551.0
If we subtract 16 from 25, we get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 16

Let's proceed to step 6:
95 divided by 16 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 25515.0
If we take 80 away from 95, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 16 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 25515.9
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 25515.93
Subtract 48 from 60 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 25515.937
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:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 25515.9375
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.

Going ahead to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25515.9375
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.

Going ahead to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25515.9375
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.

The final result is 25515.9375 with a remainder of 0.0.
