23104 ÷ 80 
We want to figure out the number of times 23104 can be divided by 80.

Step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 80

Step 2:
When dividing 23 by 80, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 80

Step 3:
The number 80 fits into 231 2 times, leaving a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 160 from 231 to get 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 80

Going ahead to step 4:
If we divide 710 by 80, we get 8 and a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 640 from 710 leaves us with 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 80

Going ahead to step 5:
If we divide 704 by 80, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 288.0
Subtract 640 from 704 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 6:
If we divide 640 by 80, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 288.8
Deduct 640 from 640 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 7:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 288.8
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.

Going ahead to step 8:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 288.8
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.

Our division results in 288.8 with a remaining 0.0.
