We look at the division of 142456 by 16 
Let's see how many times 16 fits into 142456.

Going ahead to step 1:
16 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 16

Moving on to step 2:
14 divided by 16 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 16

On to step 3:
The number 16 fits into 142 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 128 from 142 and we're left with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 16

Advancing to step 4:
If we divide 144 by 16, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 89.0
If we subtract 144 from 144, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 16

Step 5:
16 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 890.0
Subtract 0 from 5 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 16

Advancing to step 6:
16 can be fit into 56 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 8903.0
If we take 48 away from 56, we end up 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.

Moving on to step 7:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8903.5
The remainder is 0 after subtracting 80 from 80.
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 8:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8903.5
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.

Advancing to step 9:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8903.5
Deduct 0 from 0 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.

The final result is 8903.5 with a remainder of 0.0.
