Let's divide 241231 by 81
We're looking to find how many times 81 goes into 241231.

Advancing to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 81

Going ahead to step 2:
When dividing 24 by 81, we get 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 81

On to step 3:
The number 81 fits into 241 2 times, leaving a remainder of 79.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 162 from 241, we get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 81

Advancing to step 4:
If we divide 792 by 81, we get 9 and a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 729 from 792 leaves us with 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 81

Step 5:
81 can be fit into 633 7 times, resulting in a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 297.0
Deduct 567 from 633 and we're left with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 81

Advancing to step 6:
81 goes into 661 8 times with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 2978.0
Deduct 648 from 661 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
81 goes into 130 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 2978.1
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
81 goes into 490 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2978.16
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
81 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 2978.16
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
81 goes into 400 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 2978.1604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
760 divided by 81 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 2978.16049
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 2978.160493
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
If we divide 670 by 81, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2978.1604938
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 81, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 2978.16049382
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 2978.16049382 with a remainder of 5.8e-08.
