315235 divided by 30 
Let's see how many times 30 fits into 315235.

On to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 30

Going ahead to step 2:
30 goes into 31 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 30 from 31 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 30

Moving on to step 3:
30 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 30

Moving on to step 4:
When dividing 152 by 30, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 105.0
Subtracting 150 from 152 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 30

Going ahead to step 5:
30 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 1050.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 30

Going ahead to step 6:
30 can be fit into 235 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 10507.0
Subtracting 210 from 235 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
If we divide 250 by 30, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 10507.8
Deduct 240 from 250 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 10507.83
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 10507.833
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 10507.833 with a remaining 0.001.
