We look at the division of 50389 by 80 
The aim is to understand the frequency of 80 in 50389.

Let's proceed to step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 80

On to step 2:
The number 80 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 80

Going ahead to step 3:
80 can be fit into 503 6 times, resulting in a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 480 from 503, we get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 80

Let's proceed to step 4:
80 goes into 238 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtract 160 from 238 to get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 80

Step 5:
80 goes into 789 9 times with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 629.0
Subtract 720 from 789 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 6:
80 can be fit into 690 8 times, resulting in a remainder of 50.
The next digit of our result is 8. 
Result so far: 629.8
If we subtract 640 from 690, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 80, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 629.86
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 629.862
Subtracting 160 from 200 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.

Advancing to step 9:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 629.8625
Deduct 400 from 400 and we're left 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 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 629.8625
Deduct 0 from 0 and we're left 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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 629.8625
Subtracting 0 from 0 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.

The final result is 629.8625 with a remainder of 0.0.
