We look at the division of 819826 by 16 
The aim is to understand the frequency of 16 in 819826.

Advancing to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 16

Moving on to step 2:
16 goes into 81 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 80 from 81, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 16

Step 3:
19 divided by 16 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 16 from 19 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 16

Step 4:
When dividing 38 by 16, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtracting 32 from 38 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 16

Advancing to step 5:
When dividing 62 by 16, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 5123.0
If we take 48 away from 62, we end up with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 16

Let's proceed to step 6:
If we divide 146 by 16, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 51239.0
Subtract 144 from 146 to get 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 7:
16 can be fit into 20 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 51239.1
Subtracting 16 from 20 leaves us 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.

Step 8:
40 divided by 16 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 51239.12
Subtracting 32 from 40 leaves us 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.

Going ahead to step 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 51239.125
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.

Going ahead to step 10:
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: 51239.125
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51239.125
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.

The final outcome is 51239.125, with a leftover of 0.0.
