We look at the division of 449369 by 16 
The aim is to understand the frequency of 16 in 449369.

Going ahead to step 1:
When dividing 4 by 16, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 16

Let's proceed to step 2:
16 goes into 44 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 32 from 44, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 16

Let's proceed to step 3:
16 goes into 129 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 128 from 129 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 16

Let's proceed to step 4:
16 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtract 0 from 13 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 16

Let's proceed to step 5:
136 divided by 16 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 2808.0
If we subtract 128 from 136, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 16

Step 6:
If we divide 89 by 16, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 28085.0
Subtracting 80 from 89 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 16 fits into 90 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 28085.5
If we subtract 80 from 90, we get 10.
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 8:
When dividing 100 by 16, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 28085.56
Subtracting 96 from 100 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.

Going ahead to step 9:
16 goes into 40 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 28085.562
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 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 28085.5625
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.

Let's proceed to step 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28085.5625
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.

Going ahead to step 12:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 28085.5625
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 28085.5625 with a remaining 0.0.
