240731 ÷ 81 
Our goal is to divide 240731 by 81.

Going ahead to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 81

Step 2:
The number 81 fits into 24 0 times, leaving a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 81

Advancing to step 3:
240 divided by 81 is 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 2.0
If we take 162 away from 240, we end up with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 81

Let's proceed to step 4:
The number 81 fits into 787 9 times, leaving a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 58 after subtracting 729 from 787.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 81

Moving on to step 5:
81 can be fit into 583 7 times, resulting in a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
If we subtract 567 from 583, we get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 81

Going ahead to step 6:
81 goes into 161 1 times with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 2971.0
Deduct 81 from 161 and we're left with 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 7:
800 divided by 81 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 2971.9
Subtracting 729 from 800 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 8:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 2971.98
If we subtract 648 from 710, we 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.

Going ahead to step 9:
620 divided by 81 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 2971.987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
When dividing 530 by 81, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 2971.9876
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2971.98765
Deduct 405 from 440 and we're left 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.

Advancing to step 12:
When dividing 350 by 81, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2971.987654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 2971.9876543
Deduct 243 from 260 and we're left with 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 14:
81 goes into 170 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2971.98765432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 2971.98765432 with a remaining 8e-09.
