820530 ÷ 30 
We want to figure out the number of times 820530 can be divided by 30.

Let's proceed to step 1:
30 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 30

Let's proceed to step 2:
30 can be fit into 82 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 2.0
If we take 60 away from 82, we end up with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 30

Let's proceed to step 3:
The number 30 fits into 220 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 210 from 220 to get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 30

Advancing to step 4:
If we divide 105 by 30, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
Deduct 90 from 105 and we're left with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 30

Moving on to step 5:
153 divided by 30 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 2735.0
Subtract 150 from 153 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 30

Moving on to step 6:
30 goes into 30 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 27351.0
Deduct 30 from 30 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.

On to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 27351.0
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.

Moving on to step 8:
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: 27351.0
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.

In conclusion, the division gives 27351.0 with a balance of 0.0.
