We divide 409631 by 30
Our goal is to divide 409631 by 30.

Going ahead to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 30

Let's proceed to step 2:
If we divide 40 by 30, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 30 from 40 leaves us with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 30

Step 3:
When dividing 109 by 30, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 90 from 109, we get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 30

Step 4:
When dividing 196 by 30, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 180 from 196 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 30

Moving on to step 5:
163 divided by 30 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 1365.0
Subtracting 150 from 163 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 30

Step 6:
30 goes into 131 4 times with a remainder of 11.
The next digit of our result is 4. 
Result so far: 13654.0
The remainder is 11 after subtracting 120 from 131.
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:
30 can be fit into 110 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 13654.3
Deduct 90 from 110 and we're left 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.

On to step 8:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 13654.36
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 13654.366
Deduct 180 from 200 and we're left 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.

The quotient of the division is 13654.366, and the remainder is 0.002.
