We look at the division of 50919 by 80 
The aim is to understand the frequency of 80 in 50919.

Let's proceed to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 80

Let's proceed 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
If we take 0 away from 50, we end up with 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 80

Moving on to step 3:
80 can be fit into 509 6 times, resulting in a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 480 from 509 and we're left with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 80

Going ahead to step 4:
291 divided by 80 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 240 from 291 leaves us with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 80

Step 5:
519 divided by 80 is 6 with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 636.0
The remainder is 39 after subtracting 480 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 6:
If we divide 390 by 80, we get 4 and a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 636.4
If we subtract 320 from 390, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
The number 80 fits into 700 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 636.48
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 636.487
The remainder is 40 after subtracting 560 from 600.
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:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 636.4875
Subtracting 400 from 400 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 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 636.4875
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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 636.4875
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 636.4875 with a remainder of 0.0.
