We look at the division of 308370 by 30 
Our goal is to divide 308370 by 30.

Going ahead to step 1:
30 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Moving on to step 2:
If we divide 30 by 30, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 30 from 30 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 30

Let's proceed to step 3:
8 divided by 30 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 30

Let's proceed to step 4:
When dividing 83 by 30, we get 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we take 60 away from 83, we end up with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 30

Moving on to step 5:
The number 30 fits into 237 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1027.0
Deduct 210 from 237 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 30

Step 6:
270 divided by 30 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 10279.0
Subtract 270 from 270 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: 10279.0
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.

On to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10279.0
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 10279.0 with a balance of 0.0.
