We're dividing 454586 by 16 
Let's see how many times 16 fits into 454586.

Moving on to step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 16

Going ahead to step 2:
When dividing 45 by 16, we get 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 32 from 45, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 16

On to step 3:
134 divided by 16 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 128 from 134 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 16

On to step 4:
16 goes into 65 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 284.0
If we subtract 64 from 65, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 16

Going ahead to step 5:
The number 16 fits into 18 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 2841.0
If we subtract 16 from 18, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 16

Let's proceed to step 6:
If we divide 26 by 16, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 28411.0
The remainder is 10 after subtracting 16 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
100 divided by 16 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 28411.6
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 16, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 28411.62
Deduct 32 from 40 and we're left 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.

On to step 9:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 28411.625
Subtracting 80 from 80 leaves us 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.

Advancing to step 10:
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: 28411.625
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.

Moving on to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28411.625
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 outcome is 28411.625, with a leftover of 0.0.
