Let's divide 811771 by 18
We're looking to find how many times 18 goes into 811771.

Moving on to step 1:
8 divided by 18 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 18

Going ahead to step 2:
When dividing 81 by 18, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 72 from 81 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 18

Let's proceed to step 3:
If we divide 91 by 18, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 1 after subtracting 90 from 91.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 18

Let's proceed to step 4:
If we divide 17 by 18, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 450.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 18

Going ahead to step 5:
18 goes into 177 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 4509.0
The remainder is 15 after subtracting 162 from 177.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 18

Let's proceed to step 6:
151 divided by 18 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 45098.0
Deduct 144 from 151 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 45098.3
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 45098.38
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 45098.388
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 45098.388 with a remainder of 0.0016.
