We look at the division of 815613 by 30 
We're looking to find how many times 30 goes into 815613.

Going ahead to step 1:
30 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 30

Step 2:
The number 30 fits into 81 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 60 from 81 to get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 30

Advancing to step 3:
If we divide 215 by 30, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 210 from 215 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 30

Going ahead to step 4:
When dividing 56 by 30, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 271.0
If we take 30 away from 56, we end up with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 30

Going ahead to step 5:
When dividing 261 by 30, we get 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 2718.0
The remainder is 21 after subtracting 240 from 261.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 30

Let's proceed to step 6:
The number 30 fits into 213 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 27187.0
Deduct 210 from 213 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 30 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 27187.1
If we subtract 30 from 30, 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.

Advancing 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: 27187.1
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.

On to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27187.1
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.

The final result is 27187.1 with a remainder of 0.0.
