We're dividing 804220 by 16 
The aim is to understand the frequency of 16 in 804220.

Going ahead to step 1:
16 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 16

Advancing to step 2:
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: 5.0
Subtracting 80 from 80 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 16

Going ahead to step 3:
16 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 16

Advancing to step 4:
The number 16 fits into 42 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 502.0
Subtracting 32 from 42 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 16

Going ahead to step 5:
16 goes into 102 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 5026.0
If we subtract 96 from 102, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 16

Going ahead to step 6:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 50263.0
Subtract 48 from 60 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
16 goes into 120 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 50263.7
Subtracting 112 from 120 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.

Let's proceed to step 8:
80 divided by 16 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 50263.75
Subtract 80 from 80 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.

Step 9:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50263.75
If we subtract 0 from 0, 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.

Moving on to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50263.75
If we subtract 0 from 0, 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.

The final result is 50263.75 with a remainder of 0.0.
