Let's divide 402618 by 30
Let's see how many times 30 fits into 402618.

Advancing to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 30

Moving on to step 2:
30 goes into 40 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 40 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 30

On to step 3:
102 divided by 30 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 90 from 102 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 30

Going ahead to step 4:
When dividing 126 by 30, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 134.0
Subtracting 120 from 126 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 30

Going ahead to step 5:
61 divided by 30 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1342.0
If we take 60 away from 61, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 30

Let's proceed to step 6:
18 divided by 30 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 13420.0
Subtracting 0 from 18 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
The number 30 fits into 180 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 13420.6
The remainder is 0 after subtracting 180 from 180.
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 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13420.6
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.

Going ahead to step 9:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13420.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 13420.6 and a remainder of 0.0.
