We're dividing 449456 by 16 
The aim is to understand the frequency of 16 in 449456.

Step 1:
16 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 16

Advancing to step 2:
If we divide 44 by 16, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 32 from 44, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 16

Advancing to step 3:
16 goes into 129 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 128 from 129 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 16

Step 4:
The number 16 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 280.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 16

Moving on to step 5:
145 divided by 16 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2809.0
The remainder is 1 after subtracting 144 from 145.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 16

Let's proceed to step 6:
16 goes into 16 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 28091.0
If we subtract 16 from 16, 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.

Going ahead to step 7:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 28091.0
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.

Advancing to step 8:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28091.0
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 result is 28091.0 with a remainder of 0.0.
