We divide 243109 by 3
We want to divide 243109 by 3.

Let's proceed to step 1:
If we divide 2 by 3, we get 0 and 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.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Step 2:
When dividing 24 by 3, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Advancing to step 3:
3 goes into 3 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Going ahead to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 810.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Let's proceed to step 5:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 8103.0
Deduct 9 from 10 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Let's proceed to step 6:
The number 3 fits into 19 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 81036.0
If we take 18 away from 19, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 81036.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 81036.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 81036.33 with a remainder of 0.001.
