11783 divided by 80 
The aim is to understand the frequency of 80 in 11783.

On to step 1:
80 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 80

Let's proceed to step 2:
80 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 80

Moving on to step 3:
80 goes into 117 1 times with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 117 leaves us with 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 80

Step 4:
The number 80 fits into 378 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 320 from 378 and we're left with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 80

Let's proceed to step 5:
80 goes into 583 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
If we take 560 away from 583, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 6:
80 goes into 230 2 times with a remainder of 70.
The next digit of our result is 2. 
Result so far: 147.2
Deduct 160 from 230 and we're left with 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:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The next digit of our result is 8. 
Result so far: 147.28
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.

On to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.287
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 147.2875
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.

Let's proceed to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 147.2875
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 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: 147.2875
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.

After the division, we end up with 147.2875 and a remainder of 0.0.
