91183180 divided by 80 
We want to figure out the number of times 91183180 can be divided by 80.

Moving on to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 80

On to step 2:
The number 80 fits into 91 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 11 after subtracting 80 from 91.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 80

Moving on to step 3:
When dividing 111 by 80, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 80 from 111 to get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 80

On to step 4:
318 divided by 80 is 3 with a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtracting 240 from 318 leaves us with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 80

Let's proceed to step 5:
The number 80 fits into 783 9 times, leaving a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 1139.0
If we take 720 away from 783, we end up with 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 80

Advancing to step 6:
631 divided by 80 is 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 11397.0
Subtracting 560 from 631 leaves us with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 80

Step 7:
80 goes into 718 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 113978.0
If we subtract 640 from 718, we get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 80

Let's proceed to step 8:
80 goes into 780 9 times with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 1139789.0
The remainder is 60 after subtracting 720 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
600 divided by 80 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 1139789.7
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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1139789.75
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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1139789.75
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.

Step 12:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1139789.75
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.

The final result is 1139789.75 with a remainder of 0.0.
