We're dividing 23163 by 80 
The aim is to understand the frequency of 80 in 23163.

On to step 1:
80 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 80

On to step 2:
23 divided by 80 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 80

Moving on to step 3:
80 goes into 231 2 times with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 160 from 231, we get 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 80

Let's proceed to step 4:
The number 80 fits into 716 8 times, leaving a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 640 from 716 and we're left with 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 80

Step 5:
When dividing 763 by 80, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 289.0
If we take 720 away from 763, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 6:
The number 80 fits into 430 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 289.5
If we take 400 away from 430, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
80 goes into 300 3 times with a remainder of 60.
The next digit of our result is 3. 
Result so far: 289.53
Deduct 240 from 300 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.

Advancing to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 289.537
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.

On to step 9:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 289.5375
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 289.5375
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.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 289.5375
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.

The final result is 289.5375 with a remainder of 0.0.
