Let's divide 243150 by 81
We're looking to find how many times 81 goes into 243150.

Going ahead to step 1:
81 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 81

Going ahead to step 2:
If we divide 24 by 81, we get 0 and a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 81

Advancing to step 3:
81 can be fit into 243 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 243 from 243 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 81

Let's proceed to step 4:
1 divided by 81 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 81

On to step 5:
81 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
Subtract 0 from 15 to get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 81

Let's proceed to step 6:
The number 81 fits into 150 1 times, leaving a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 3001.0
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
When dividing 690 by 81, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 3001.8
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
420 divided by 81 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3001.85
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 81 is 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 3001.851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 10:
When dividing 690 by 81, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 3001.8518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
If we divide 420 by 81, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3001.85185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
81 can be fit into 150 1 times, resulting in a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 3001.851851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 13:
When dividing 690 by 81, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 3001.8518518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
81 goes into 420 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3001.85185185
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 3001.85185185, with a leftover of 1.5e-08.
