844080 ÷ 16 
The aim is to understand the frequency of 16 in 844080.

Let's proceed to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 16

Let's proceed to step 2:
84 divided by 16 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 80 from 84 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 16

Advancing to step 3:
44 divided by 16 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 32 away from 44, we end up with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 16

On to step 4:
The number 16 fits into 120 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 527.0
If we take 112 away from 120, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 16

Going ahead to step 5:
88 divided by 16 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5275.0
Subtracting 80 from 88 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 16

Advancing to step 6:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 52755.0
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.

Advancing to step 7:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 52755.0
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.

Step 8:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 52755.0
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.

After the division, we end up with 52755.0 and a remainder of 0.0.
