We're dividing 52087 by 80 
The aim is to understand the frequency of 80 in 52087.

Step 1:
5 divided by 80 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 80

Advancing to step 2:
The number 80 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 80

Step 3:
80 can be fit into 520 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 480 from 520 leaves us with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 80

Let's proceed to step 4:
If we divide 408 by 80, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 8 after subtracting 400 from 408.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 80

Advancing to step 5:
If we divide 87 by 80, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
If we subtract 80 from 87, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 6:
If we divide 70 by 80, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 651.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
700 divided by 80 is 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 651.08
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 651.087
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 651.0875
Subtract 400 from 400 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.

Let's proceed to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 651.0875
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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 651.0875
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 651.0875 and a remainder of 0.0.
