We look at the division of 990768 by 16 
The aim is to understand the frequency of 16 in 990768.

Moving on to step 1:
16 goes into 9 0 times 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.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 16

Going ahead to step 2:
The number 16 fits into 99 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 96 from 99, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 16

Moving on to step 3:
16 goes into 30 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 16 from 30 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 16

Step 4:
If we divide 147 by 16, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 619.0
If we take 144 away from 147, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 16

On to step 5:
16 goes into 36 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 6192.0
Subtracting 32 from 36 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 16

On to step 6:
48 divided by 16 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 61923.0
If we subtract 48 from 48, 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.

Step 7:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61923.0
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.

Going ahead to step 8:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61923.0
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.

Our division results in 61923.0 with a remaining 0.0.
