318266 ÷ 81 
Our goal is to divide 318266 by 81.

Let's proceed to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 81

Moving on to step 2:
81 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 81

Let's proceed to step 3:
318 divided by 81 is 3 with a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 243 from 318 to get 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 81

On to step 4:
81 goes into 752 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 729 from 752 to get 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 81

Advancing to step 5:
If we divide 236 by 81, we get 2 and a remainder of 74.
The next digit of our result is 2. 
Result so far: 392.0
Subtract 162 from 236 to get 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 81

Going ahead to step 6:
746 divided by 81 is 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 3929.0
If we subtract 729 from 746, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 81 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3929.2
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
81 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 3929.2
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
When dividing 800 by 81, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 3929.209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
When dividing 710 by 81, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 3929.2098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
81 goes into 620 7 times with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 3929.20987
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 12:
81 goes into 530 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 3929.209876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3929.2098765
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
350 divided by 81 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 3929.20987654
Subtracting 324 from 350 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 3929.20987654 with a remainder of 2.6e-08.
