186582 ÷ 81 
We want to figure out the number of times 186582 can be divided by 81.

Let's proceed to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 81

Step 2:
The number 81 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 81

Let's proceed to step 3:
186 divided by 81 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 162 away from 186, we end up with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 81

Going ahead to step 4:
When dividing 245 by 81, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 2 after subtracting 243 from 245.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 81

Going ahead to step 5:
When dividing 28 by 81, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 230.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 81

Step 6:
81 goes into 282 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 2303.0
If we take 243 away from 282, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
81 goes into 390 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 2303.4
Subtracting 324 from 390 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
81 goes into 660 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2303.48
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
81 can be fit into 120 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 2303.481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 2303.4814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2303.48148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
81 can be fit into 120 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 2303.481481
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
81 goes into 390 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 2303.4814814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
If we divide 660 by 81, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 2303.48148148
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 2303.48148148 with a remainder of 1.2e-08.
