We're dividing 345320 by 30 
Let's see how many times 30 fits into 345320.

Going ahead to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 30

Let's proceed to step 2:
34 divided by 30 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 30 from 34 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 30

Step 3:
45 divided by 30 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 30 from 45, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 30

Advancing to step 4:
If we divide 153 by 30, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 150 from 153, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 30

Going ahead to step 5:
When dividing 32 by 30, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1151.0
Deduct 30 from 32 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 30

Moving on to step 6:
The number 30 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11510.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 11510.6
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 11510.66
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 11510.66 with a balance of 0.02.
