We're dividing 555378 by 30 
Let's see how many times 30 fits into 555378.

On to step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 30

Going ahead to step 2:
The number 30 fits into 55 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 30 from 55, we get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 30

Step 3:
30 can be fit into 255 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 240 from 255 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 30

On to step 4:
If we divide 153 by 30, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 185.0
The remainder is 3 after subtracting 150 from 153.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 30

On to step 5:
When dividing 37 by 30, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1851.0
Subtract 30 from 37 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 30

Step 6:
30 goes into 78 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 18512.0
Subtracting 60 from 78 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.

Let's proceed to step 7:
The number 30 fits into 180 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 18512.6
Subtracting 180 from 180 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.

Let's proceed to step 8:
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: 18512.6
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.

Advancing to step 9:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18512.6
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 outcome is 18512.6, with a leftover of 0.0.
