We're dividing 305223 by 30 
We want to figure out the number of times 305223 can be divided by 30.

Advancing to step 1:
3 divided by 30 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Moving on to step 2:
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: 1.0
If we subtract 30 from 30, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 30

Moving on to step 3:
The number 30 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 30

Moving on to step 4:
30 can be fit into 52 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 30 from 52 to get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 30

Going ahead to step 5:
The number 30 fits into 222 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 1017.0
Subtracting 210 from 222 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 30

Moving on to step 6:
30 goes into 123 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 10174.0
If we take 120 away from 123, we end up 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:
If we divide 30 by 30, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 10174.1
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.

Let's proceed to step 8:
30 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10174.1
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.

Going ahead to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10174.1
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.

In conclusion, the division gives 10174.1 with a balance of 0.0.
