457649 ÷ 16 
Our goal is to divide 457649 by 16.

Let's proceed to step 1:
4 divided by 16 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 16

Let's proceed 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
Subtracting 32 from 45 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 16

Let's proceed to step 3:
When dividing 137 by 16, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 128 away from 137, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 16

Let's proceed to step 4:
When dividing 96 by 16, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
If we take 96 away from 96, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 16

Going ahead to step 5:
When dividing 4 by 16, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 2860.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 16

Step 6:
16 goes into 49 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 28603.0
Subtract 48 from 49 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 16 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 28603.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
16 goes into 100 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 28603.06
Subtract 96 from 100 to 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 9:
16 goes into 40 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 28603.062
The remainder is 8 after subtracting 32 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 28603.0625
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.

Advancing to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 28603.0625
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.

On to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28603.0625
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.

The final outcome is 28603.0625, with a leftover of 0.0.
