308394 ÷ 81 
We're looking to find how many times 81 goes into 308394.

Moving on to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 81

Moving on to step 2:
When dividing 30 by 81, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 81

Going ahead to step 3:
308 divided by 81 is 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 243 from 308 leaves us with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 81

Advancing to step 4:
The number 81 fits into 653 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 648 from 653 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 81

Advancing to step 5:
If we divide 59 by 81, we get 0 and a remainder of 59.
The next digit of our result is 0. 
Result so far: 380.0
Subtracting 0 from 59 leaves us with 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 81

Let's proceed to step 6:
When dividing 594 by 81, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 3807.0
Subtract 567 from 594 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
81 goes into 270 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 3807.3
The remainder is 27 after subtracting 243 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
The number 81 fits into 270 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 3807.33
Subtract 243 from 270 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 3807.33 with a remaining 0.027.
