185805 ÷ 81 
We want to figure out the number of times 185805 can be divided by 81.

On to step 1:
81 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 81

Step 2:
81 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 81

Step 3:
185 divided by 81 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 162 from 185 leaves us with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 81

Let's proceed to step 4:
81 can be fit into 238 2 times, resulting in a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 162 from 238 leaves us with 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 81

On to step 5:
760 divided by 81 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
If we take 729 away from 760, we end up with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 81

Moving on to step 6:
The number 81 fits into 315 3 times, leaving a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 2293.0
If we subtract 243 from 315, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
81 goes into 720 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 2293.8
The remainder is 72 after subtracting 648 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
If we divide 720 by 81, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 2293.88
If we subtract 648 from 720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 2293.88 with a remainder of 0.072.
