We divide 11280811 by 80
We want to figure out the number of times 11280811 can be divided by 80.

Advancing to step 1:
80 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 80

Advancing to step 2:
80 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 80

Going ahead to step 3:
When dividing 112 by 80, we get 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 112, we end up with 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 80

Going ahead to step 4:
If we divide 328 by 80, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 320 away from 328, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 80

Let's proceed to step 5:
80 divided by 80 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 141.0
If we subtract 80 from 80, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 80

On to step 6:
80 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 1410.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 80

Moving on to step 7:
80 can be fit into 81 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 14101.0
If we subtract 80 from 81, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 80

Advancing to step 8:
The number 80 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 141010.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
110 divided by 80 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 141010.1
If we take 80 away from 110, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
80 goes into 300 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 141010.13
If we take 240 away from 300, we end up 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.

Advancing to step 11:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 141010.137
If we take 560 away from 600, we end up with 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 12:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 141010.1375
If we subtract 400 from 400, 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.

Let's proceed to step 13:
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: 141010.1375
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.

Moving on to step 14:
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: 141010.1375
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.

After the division, we end up with 141010.1375 and a remainder of 0.0.
