Let's divide 243134 by 81
We're looking to find how many times 81 goes into 243134.

Step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 81

Step 2:
If we divide 24 by 81, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 81

Moving on to step 3:
81 can be fit into 243 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we take 243 away from 243, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 81

Step 4:
81 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 81

On to step 5:
81 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 300.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 81

Let's proceed to step 6:
When dividing 134 by 81, we get 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 3001.0
The remainder is 53 after subtracting 81 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 81 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3001.6
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.

Going ahead to step 8:
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: 3001.65
Subtracting 405 from 440 leaves us 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 9:
81 goes into 350 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3001.654
The remainder is 26 after subtracting 324 from 350.
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 10:
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: 3001.6543
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.

Moving on to step 11:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3001.65432
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.

Advancing to step 12:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 3001.65432
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.

Going ahead to step 13:
81 goes into 800 9 times with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 3001.6543209
If we subtract 729 from 800, we 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.

On to step 14:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 3001.65432098
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.

The final result is 3001.65432098 with a remainder of 6.2e-08.
