We're dividing 393484 by 30 
Let's see how many times 30 fits into 393484.

Moving on to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 30

Moving 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
Deduct 30 from 39 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 30

Going ahead to step 3:
93 divided by 30 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 90 from 93 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 30

On to step 4:
The number 30 fits into 34 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 30 from 34 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 30

On to step 5:
If we divide 48 by 30, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1311.0
If we take 30 away from 48, we end up with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 30

Advancing to step 6:
184 divided by 30 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 13116.0
If we subtract 180 from 184, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 30, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 13116.1
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 13116.13
If we subtract 90 from 100, we get 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 9:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 13116.133
Subtracting 90 from 100 leaves us 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 13116.133 and a remainder of 0.001.
