We look at the division of 80585579 by 918 
We want to figure out the number of times 80585579 can be divided by 918.

On to step 1:
If we divide 8 by 918, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 918

On to step 2:
When dividing 80 by 918, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 918

Step 3:
918 can be fit into 805 0 times, resulting in a remainder of 805.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 805 and we're left with 805.
Grab the next digit (8) from the dividend, add it to 805, then carry on: 8058 / 918

Advancing to step 4:
8058 divided by 918 is 8 with a remainder of 714.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 7344 from 8058, we get 714.
Fetch the next digit (5) from the dividend, attach it to 714 and continue: 7145 / 918

On to step 5:
918 can be fit into 7145 7 times, resulting in a remainder of 719.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 6426 from 7145 and we're left with 719.
Include the next digit (5) from the dividend after 719, then repeat: 7195 / 918

Let's proceed to step 6:
The number 918 fits into 7195 7 times, leaving a remainder of 769.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
The remainder is 769 after subtracting 6426 from 7195.
Include the next digit (7) from the dividend after 769, then repeat: 7697 / 918

Advancing to step 7:
When dividing 7697 by 918, we get 8 with a remainder of 353.
Write down 8 as next digit of the result. 
Result so far: 8778.0
If we take 7344 away from 7697, we end up with 353.
Append the next digit (9) from the dividend to 353 and continue with: 3539 / 918

Advancing to step 8:
3539 divided by 918 is 3 with a remainder of 785.
Use 3 as the next digit of our solution. 
Result so far: 87783.0
Subtract 2754 from 3539 to get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Step 9:
The number 918 fits into 7850 8 times, leaving a remainder of 506.
Record the quotient 8 as the next digit in the result. 
Result so far: 87783.8
Deduct 7344 from 7850 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 10:
918 goes into 5060 5 times with a remainder of 470.
Put 5 as the next digit of the answer. 
Result so far: 87783.85
If we take 4590 away from 5060, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 11:
If we divide 4700 by 918, we get 5 and a remainder of 110.
The next digit of our result is 5. 
Result so far: 87783.855
Deduct 4590 from 4700 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Our division results in 87783.855 with a remaining 0.011.
