Let's divide 159004 by 80
The aim is to understand the frequency of 80 in 159004.

Moving on to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 80

Let's proceed to step 2:
When dividing 15 by 80, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 80

On to step 3:
If we divide 159 by 80, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 159, we get 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 80

Moving on to step 4:
80 goes into 790 9 times with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 720 from 790 to get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 80

Going ahead to step 5:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 198.0
If we take 640 away from 700, we end up with 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 80

Moving on to step 6:
80 goes into 604 7 times with a remainder of 44.
The next digit of our result is 7. 
Result so far: 1987.0
Subtract 560 from 604 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
When dividing 440 by 80, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1987.5
The remainder is 40 after subtracting 400 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1987.55
If we take 400 away from 400, 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.

After the division, we end up with 1987.55 and a remainder of 0.0.
