230891 ÷ 80 
We want to figure out the number of times 230891 can be divided by 80.

Step 1:
80 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
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

Going ahead to step 2:
The number 80 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 80

On to step 3:
The number 80 fits into 230 2 times, leaving a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 70 after subtracting 160 from 230.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 80

On to step 4:
80 goes into 708 8 times with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 640 from 708, we get 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 80

Advancing to step 5:
When dividing 689 by 80, we get 8 with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
The remainder is 49 after subtracting 640 from 689.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 80

On to step 6:
When dividing 491 by 80, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 2886.0
Subtracting 480 from 491 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 80, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 2886.1
If we subtract 80 from 110, 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.

Let's proceed to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 2886.13
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 80 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 2886.137
Subtract 560 from 600 to 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.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2886.1375
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:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2886.1375
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.

Moving on to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2886.1375
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 2886.1375 with a remaining 0.0.
