We look at the division of 236955 by 80 
The aim is to understand the frequency of 80 in 236955.

Going ahead to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 80

Step 2:
80 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 80

Advancing to step 3:
If we divide 236 by 80, we get 2 and a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 160 from 236, we get 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 80

On to step 4:
80 can be fit into 769 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 720 from 769 and we're left with 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 80

Step 5:
495 divided by 80 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 296.0
Deduct 480 from 495 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 80

Going ahead to step 6:
80 can be fit into 155 1 times, resulting in a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 2961.0
Deduct 80 from 155 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 7:
80 can be fit into 750 9 times, resulting in a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 2961.9
If we subtract 720 from 750, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 2961.93
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.

Step 9:
600 divided by 80 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 2961.937
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 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2961.9375
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.

Advancing to step 11:
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: 2961.9375
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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2961.9375
Subtract 0 from 0 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.

Our division results in 2961.9375 with a remaining 0.0.
