We're dividing 30409507 by 331 
We want to divide 30409507 by 331.

Moving on to step 1:
3 divided by 331 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 331

On to step 2:
331 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 331

Step 3:
331 can be fit into 304 0 times, resulting in a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 304, we get 304.
Grab the next digit (0) from the dividend, add it to 304, then carry on: 3040 / 331

Going ahead to step 4:
331 goes into 3040 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 2979 from 3040 to get 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 331

Going ahead to step 5:
619 divided by 331 is 1 with a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 331 from 619, we get 288.
Take the next digit (5) from the dividend and append it to 288, then repeat: 2885 / 331

Let's proceed to step 6:
331 goes into 2885 8 times with a remainder of 237.
Record the quotient 8 as the next digit in the result. 
Result so far: 918.0
Deduct 2648 from 2885 and we're left with 237.
Include the next digit (0) from the dividend after 237, then repeat: 2370 / 331

Let's proceed to step 7:
331 goes into 2370 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 9187.0
Deduct 2317 from 2370 and we're left with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 331

Going ahead to step 8:
331 goes into 537 1 times with a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 91871.0
Subtracting 331 from 537 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 9:
If we divide 2060 by 331, we get 6 and a remainder of 74.
The next digit of our result is 6. 
Result so far: 91871.6
Deduct 1986 from 2060 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 331, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 91871.62
Subtract 662 from 740 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
331 goes into 780 2 times with a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 91871.622
Deduct 662 from 780 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

In conclusion, the division gives 91871.622 with a balance of 0.0118.
