909131 ÷ 80 
We want to figure out the number of times 909131 can be divided by 80.

Advancing to step 1:
80 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 80

Going ahead to step 2:
The number 80 fits into 90 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 90 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 80

On to step 3:
When dividing 109 by 80, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 80 from 109 to get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 80

On to step 4:
80 goes into 291 3 times with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 113.0
The remainder is 51 after subtracting 240 from 291.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 80

Moving on to step 5:
80 can be fit into 513 6 times, resulting in a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 1136.0
Deduct 480 from 513 and we're left with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 80

Step 6:
When dividing 331 by 80, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 11364.0
If we take 320 away from 331, we end up 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.

Advancing to step 7:
80 can be fit into 110 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11364.1
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.

On to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 11364.13
If we subtract 240 from 300, we 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.

Advancing 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: 11364.137
The remainder is 40 after subtracting 560 from 600.
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 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: 11364.1375
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.

On 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: 11364.1375
If we take 0 away from 0, 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 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: 11364.1375
If we take 0 away from 0, 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.

After the division, we end up with 11364.1375 and a remainder of 0.0.
