We look at the division of 72390 by 30 
Our goal is to divide 72390 by 30.

On to step 1:
The number 30 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 30

On to step 2:
If we divide 72 by 30, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 60 from 72 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 30

Let's proceed to step 3:
30 can be fit into 123 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 3 after subtracting 120 from 123.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 30

Moving on to step 4:
The number 30 fits into 39 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 241.0
If we take 30 away from 39, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 30

Advancing to step 5:
When dividing 90 by 30, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2413.0
Subtracting 90 from 90 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.

Advancing to step 6:
If we divide 0 by 30, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2413.0
If we subtract 0 from 0, we 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.

Going ahead to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2413.0
If we subtract 0 from 0, we 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.

Our division results in 2413.0 with a remaining 0.0.
