We look at the division of 99326573 by 16 
The aim is to understand the frequency of 16 in 99326573.

Going ahead to step 1:
9 divided by 16 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 16

Moving on to step 2:
99 divided by 16 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 96 from 99 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 16

On to step 3:
The number 16 fits into 33 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtracting 32 from 33 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 16

Advancing to step 4:
16 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 620.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 16

On to step 5:
16 can be fit into 126 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 6207.0
Subtract 112 from 126 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 16

Advancing to step 6:
16 can be fit into 145 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 62079.0
Subtract 144 from 145 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 16

Step 7:
16 can be fit into 17 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 620791.0
Deduct 16 from 17 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 16

Step 8:
When dividing 13 by 16, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 6207910.0
Subtracting 0 from 13 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
If we divide 130 by 16, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 6207910.8
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.

Going ahead to step 10:
The number 16 fits into 20 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 6207910.81
If we take 16 away from 20, we end up 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.

Let's proceed to step 11:
40 divided by 16 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 6207910.812
Deduct 32 from 40 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.

Moving on to step 12:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6207910.8125
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.

Advancing to step 13:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6207910.8125
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 14:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6207910.8125
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 quotient of the division is 6207910.8125, and the remainder is 0.0.
