We're dividing 80511 by 18 
We're looking to find how many times 18 goes into 80511.

Step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 18

Moving on to step 2:
18 goes into 80 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
If we take 72 away from 80, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 18

Advancing to step 3:
The number 18 fits into 85 4 times, leaving a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 72 from 85 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 18

Going ahead to step 4:
The number 18 fits into 131 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 447.0
Subtracting 126 from 131 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 18

Let's proceed to step 5:
18 can be fit into 51 2 times, resulting in a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 4472.0
Deduct 36 from 51 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
When dividing 150 by 18, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 4472.8
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
18 goes into 60 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 4472.83
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 4472.833
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 4472.833, and the remainder is 0.0006.
