We look at the division of 366423 by 30 
Our goal is to divide 366423 by 30.

Step 1:
3 divided by 30 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 30

Advancing to step 2:
When dividing 36 by 30, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 30 from 36 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 30

Advancing to step 3:
The number 30 fits into 66 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 60 from 66 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 30

Let's proceed to step 4:
If we divide 64 by 30, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we subtract 60 from 64, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 30

Step 5:
30 goes into 42 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1221.0
If we subtract 30 from 42, we get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 30

Let's proceed to step 6:
When dividing 123 by 30, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 12214.0
Subtract 120 from 123 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 goes into 30 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 12214.1
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.

On to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12214.1
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.

Step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 12214.1
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 final result is 12214.1 with a remainder of 0.0.
