Let's divide 811899 by 18
We're looking to find how many times 18 goes into 811899.

Going ahead to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 18

Going ahead to step 2:
18 goes into 81 4 times with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 72 away from 81, we end up 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:
18 goes into 91 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 90 from 91, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 18

Advancing to step 4:
The number 18 fits into 18 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
If we take 18 away from 18, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 18

Going ahead to step 5:
When dividing 9 by 18, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 4510.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 18

On to step 6:
18 goes into 99 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 45105.0
The remainder is 9 after subtracting 90 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 18, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45105.5
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45105.5
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.

On to step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45105.5
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.

Our division results in 45105.5 with a remaining 0.0.
