We look at the division of 448413 by 16 
We want to figure out the number of times 448413 can be divided by 16.

Let's proceed to step 1:
16 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 16

Moving on to step 2:
The number 16 fits into 44 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 32 from 44 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 16

On to step 3:
128 divided by 16 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 128 away from 128, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 16

Going ahead to step 4:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 280.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 16

Going ahead to step 5:
16 can be fit into 41 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 2802.0
The remainder is 9 after subtracting 32 from 41.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 16

Going ahead to step 6:
If we divide 93 by 16, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 28025.0
The remainder is 13 after subtracting 80 from 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
16 can be fit into 130 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 28025.8
If we take 128 away from 130, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
16 can be fit into 20 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 28025.81
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 16, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 28025.812
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.

On to step 10:
16 goes into 80 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 28025.8125
If we subtract 80 from 80, 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 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28025.8125
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 12:
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: 28025.8125
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.

After the division, we end up with 28025.8125 and a remainder of 0.0.
