We look at the division of 648564 by 16 
We want to divide 648564 by 16.

Going ahead to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Advancing to step 2:
16 goes into 64 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 64 from 64.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 16

On to step 3:
The number 16 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 16

Going ahead to step 4:
When dividing 85 by 16, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 405.0
Deduct 80 from 85 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 16

Going ahead to step 5:
16 goes into 56 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 4053.0
Deduct 48 from 56 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 16

Let's proceed to step 6:
When dividing 84 by 16, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 40535.0
If we subtract 80 from 84, 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.

Going ahead to step 7:
When dividing 40 by 16, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 40535.2
Subtract 32 from 40 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.

Step 8:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 40535.25
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 9:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40535.25
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.

Let's proceed to step 10:
When dividing 0 by 16, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40535.25
Subtracting 0 from 0 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.

Our division results in 40535.25 with a remaining 0.0.
