We look at the division of 541066 by 16 
The aim is to understand the frequency of 16 in 541066.

Let's proceed to step 1:
When dividing 5 by 16, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 16

On to step 2:
16 goes into 54 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 48 from 54, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 16

Moving on to step 3:
16 can be fit into 61 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 48 from 61 and we're left with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 16

On to step 4:
130 divided by 16 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 338.0
If we take 128 away from 130, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 16

Step 5:
When dividing 26 by 16, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3381.0
Deduct 16 from 26 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 16

Moving on to step 6:
The number 16 fits into 106 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 33816.0
The remainder is 10 after subtracting 96 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 16, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 33816.6
If we take 96 away from 100, 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.

Moving on to step 8:
40 divided by 16 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 33816.62
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.

On to step 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 33816.625
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.

Moving on to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33816.625
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.

Going ahead to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33816.625
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.

Our division results in 33816.625 with a remaining 0.0.
