We're dividing 242531 by 81 
We want to divide 242531 by 81.

Going ahead to step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 81

Advancing to step 2:
When dividing 24 by 81, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 81

Going ahead to step 3:
The number 81 fits into 242 2 times, leaving a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 162 from 242 leaves us with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 81

Let's proceed to step 4:
If we divide 805 by 81, we get 9 and a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 76 after subtracting 729 from 805.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 81

Advancing to step 5:
763 divided by 81 is 9 with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 299.0
Subtracting 729 from 763 leaves us with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 81

Step 6:
When dividing 341 by 81, we get 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 2994.0
If we take 324 away from 341, we end up 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.

Going ahead to step 7:
81 goes into 170 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2994.2
Subtracting 162 from 170 leaves us 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.

Advancing 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: 2994.2
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
When dividing 800 by 81, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 2994.209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 2994.2098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
The number 81 fits into 620 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 2994.20987
If we take 567 away from 620, we end up 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.

Advancing to step 12:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2994.209876
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.

Step 13:
When dividing 440 by 81, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 2994.2098765
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.

On to step 14:
The number 81 fits into 350 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2994.20987654
Deduct 324 from 350 and we're left 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.

Our division results in 2994.20987654 with a remaining 2.6e-08.
