We're dividing 870576 by 16 
The aim is to understand the frequency of 16 in 870576.

Let's proceed to step 1:
If we divide 8 by 16, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 16

On to step 2:
16 goes into 87 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 80 from 87 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 16

Going ahead to step 3:
The number 16 fits into 70 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 64 from 70 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 16

On to step 4:
If we divide 65 by 16, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 544.0
If we take 64 away from 65, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 16

Let's proceed to step 5:
16 goes into 17 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 5441.0
Deduct 16 from 17 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 16

Advancing to step 6:
16 can be fit into 16 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 54411.0
If we subtract 16 from 16, 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.

Step 7:
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: 54411.0
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.

Advancing to step 8:
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: 54411.0
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 54411.0 and a remainder of 0.0.
