Let's divide 331240 by 30
We want to figure out the number of times 331240 can be divided by 30.

Advancing to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 30

Moving on to step 2:
The number 30 fits into 33 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 33 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 30

Let's proceed to step 3:
30 goes into 31 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 30 from 31, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 30

Going ahead to step 4:
30 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 30

Step 5:
When dividing 124 by 30, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1104.0
Deduct 120 from 124 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 30

Step 6:
If we divide 40 by 30, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 11041.0
Deduct 30 from 40 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 11041.3
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 11041.33
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 11041.33 and a remainder of 0.01.
