We look at the division of 492180 by 16 
The aim is to understand the frequency of 16 in 492180.

Step 1:
16 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 16

Going ahead to step 2:
49 divided by 16 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 48 from 49, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 16

On to step 3:
16 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 16

Step 4:
The number 16 fits into 121 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 307.0
The remainder is 9 after subtracting 112 from 121.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 16

Moving on to step 5:
The number 16 fits into 98 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 3076.0
Subtract 96 from 98 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 16

Let's proceed to step 6:
The number 16 fits into 20 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 30761.0
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 30761.2
If we subtract 32 from 40, we 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.

On to step 8:
When dividing 80 by 16, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 30761.25
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 9:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30761.25
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 10:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30761.25
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.

After the division, we end up with 30761.25 and a remainder of 0.0.
