391413 ÷ 30 
Our goal is to divide 391413 by 30.

On to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 30

On to step 2:
When dividing 39 by 30, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 30 from 39.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 30

Moving on to step 3:
30 goes into 91 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 1 after subtracting 90 from 91.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 30

Advancing to step 4:
30 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 130.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 30

Moving on to step 5:
The number 30 fits into 141 4 times, leaving a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 1304.0
The remainder is 21 after subtracting 120 from 141.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 30

Step 6:
The number 30 fits into 213 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 13047.0
The remainder is 3 after subtracting 210 from 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 can be fit into 30 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 13047.1
Subtracting 30 from 30 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13047.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13047.1
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 13047.1, and the remainder is 0.0.
