We divide 402456 by 16
Let's see how many times 16 fits into 402456.

Going ahead to step 1:
If we divide 4 by 16, we get 0 and 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.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 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
The remainder is 8 after subtracting 32 from 40.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 16

On to step 3:
16 can be fit into 82 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 80 from 82 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 16

Let's proceed to step 4:
The number 16 fits into 24 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 251.0
If we take 16 away from 24, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 16

Going ahead to step 5:
When dividing 85 by 16, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2515.0
If we subtract 80 from 85, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 16

Advancing to step 6:
If we divide 56 by 16, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 25153.0
Subtract 48 from 56 to 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.

On to step 7:
If we divide 80 by 16, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25153.5
If we subtract 80 from 80, 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.

On to step 8:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 25153.5
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.

Going ahead to step 9:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25153.5
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.

Our division results in 25153.5 with a remaining 0.0.
