11071285 ÷ 80 
We're looking to find how many times 80 goes into 11071285.

Let's proceed to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 80

Let's proceed to step 2:
If we divide 11 by 80, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 80

Moving on to step 3:
The number 80 fits into 110 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 80 from 110 to get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 80

Going ahead to step 4:
When dividing 307 by 80, we get 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 67 after subtracting 240 from 307.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 80

Going ahead to step 5:
671 divided by 80 is 8 with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtracting 640 from 671 leaves us with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 80

Advancing to step 6:
80 goes into 312 3 times with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 1383.0
If we subtract 240 from 312, we get 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 80

Let's proceed to step 7:
80 can be fit into 728 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 13839.0
Subtracting 720 from 728 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 80

Let's proceed to step 8:
When dividing 85 by 80, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 138391.0
If we take 80 away from 85, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 80 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 138391.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 138391.06
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 138391.062
Subtracting 160 from 200 leaves us 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.

On to step 12:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 138391.0625
If we take 400 away from 400, we end up 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.

Step 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 138391.0625
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.

Let's proceed to step 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 138391.0625
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 final result is 138391.0625 with a remainder of 0.0.
