We look at the division of 456912 by 16 
We want to divide 456912 by 16.

Moving on 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
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 16

On to step 2:
16 can be fit into 45 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 13 after subtracting 32 from 45.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 16

Going ahead to step 3:
The number 16 fits into 136 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 8 after subtracting 128 from 136.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 16

Advancing to step 4:
16 can be fit into 89 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Deduct 80 from 89 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 16

Advancing to step 5:
91 divided by 16 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 2855.0
If we subtract 80 from 91, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 16

Let's proceed to step 6:
16 can be fit into 112 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 28557.0
Subtract 112 from 112 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.

On to step 7:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28557.0
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 8:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28557.0
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 outcome is 28557.0, with a leftover of 0.0.
