We look at the division of 844551 by 16 
The aim is to understand the frequency of 16 in 844551.

Going ahead to step 1:
The number 16 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 16

Advancing to step 2:
When dividing 84 by 16, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 80 from 84 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 16

Moving on to step 3:
16 goes into 44 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 32 from 44 leaves us with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 16

Let's proceed to step 4:
If we divide 125 by 16, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 527.0
Deduct 112 from 125 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 16

Moving on to step 5:
The number 16 fits into 135 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 5278.0
The remainder is 7 after subtracting 128 from 135.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 16

Step 6:
71 divided by 16 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 52784.0
Deduct 64 from 71 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 16, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 52784.4
The remainder is 6 after subtracting 64 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 52784.43
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
16 goes into 120 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 52784.437
Deduct 112 from 120 and we're left with 8.
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:
80 divided by 16 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 52784.4375
The remainder is 0 after subtracting 80 from 80.
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 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 52784.4375
Subtract 0 from 0 to 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 12:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 52784.4375
The remainder is 0 after subtracting 0 from 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 quotient of the division is 52784.4375, and the remainder is 0.0.
