We look at the division of 933989 by 80 
The aim is to understand the frequency of 80 in 933989.

Let's proceed to step 1:
80 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 80

Step 2:
80 can be fit into 93 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 80 from 93 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 80

On to step 3:
If we divide 133 by 80, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 80 from 133 leaves us with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 80

Step 4:
80 goes into 539 6 times with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtract 480 from 539 to get 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 80

Advancing to step 5:
598 divided by 80 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1167.0
Subtracting 560 from 598 leaves us with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 80

Step 6:
389 divided by 80 is 4 with a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 11674.0
If we take 320 away from 389, we end up with 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 7:
80 goes into 690 8 times with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 11674.8
Deduct 640 from 690 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 11674.86
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 11674.862
Deduct 160 from 200 and we're left 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11674.8625
The remainder is 0 after subtracting 400 from 400.
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 11:
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: 11674.8625
If we take 0 away from 0, 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.

Advancing to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11674.8625
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.

Our division results in 11674.8625 with a remaining 0.0.
