815130 ÷ 30 
We want to divide 815130 by 30.

Advancing to step 1:
30 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 30

Going ahead to step 2:
81 divided by 30 is 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 21 after subtracting 60 from 81.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 30

On to step 3:
30 goes into 215 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 5 after subtracting 210 from 215.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 30

Moving on to step 4:
30 can be fit into 51 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
The remainder is 21 after subtracting 30 from 51.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 30

Let's proceed to step 5:
30 can be fit into 213 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2717.0
If we take 210 away from 213, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 30

Moving on to step 6:
When dividing 30 by 30, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 27171.0
Subtract 30 from 30 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.

Let's proceed to step 7:
When dividing 0 by 30, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27171.0
If we take 0 away from 0, we end up 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.

Moving on to step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27171.0
The remainder is 0 after subtracting 0 from 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 27171.0, with a leftover of 0.0.
