180911 ÷ 80 
Let's see how many times 80 fits into 180911.

Going ahead to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 80

On to step 2:
When dividing 18 by 80, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 80

Going ahead to step 3:
180 divided by 80 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 160 away from 180, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 80

Let's proceed to step 4:
The number 80 fits into 209 2 times, leaving a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 160 from 209 and we're left with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 80

Step 5:
80 goes into 491 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we subtract 480 from 491, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 80

Going ahead to step 6:
111 divided by 80 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 2261.0
If we take 80 away from 111, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
80 can be fit into 310 3 times, resulting in a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 2261.3
Deduct 240 from 310 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.

On to step 8:
700 divided by 80 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 2261.38
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.

Going ahead to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 2261.387
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.

Moving on to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2261.3875
Subtracting 400 from 400 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.

Advancing to 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: 2261.3875
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.

Going ahead to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2261.3875
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.

The quotient of the division is 2261.3875, and the remainder is 0.0.
