We're dividing 231431 by 30 
We want to divide 231431 by 30.

Moving on to step 1:
30 can be fit into 2 0 times, resulting in 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.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 30

On to step 2:
If we divide 23 by 30, we get 0 and a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 30

Advancing to step 3:
If we divide 231 by 30, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 210 from 231 to get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 30

Let's proceed to step 4:
If we divide 214 by 30, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we take 210 away from 214, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 30

Step 5:
30 goes into 43 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 771.0
If we take 30 away from 43, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 30

Step 6:
When dividing 131 by 30, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 7714.0
If we take 120 away from 131, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 30 fits into 110 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 7714.3
Subtract 90 from 110 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7714.36
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7714.366
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 7714.366 with a remaining 0.002.
