We look at the division of 912430 by 30 
Let's see how many times 30 fits into 912430.

On to step 1:
When dividing 9 by 30, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 30

On to step 2:
When dividing 91 by 30, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 90 from 91 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

Advancing to step 3:
30 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 30

Going ahead to step 4:
30 goes into 124 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 304.0
Deduct 120 from 124 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 30

Moving on to step 5:
When dividing 43 by 30, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 3041.0
If we take 30 away from 43, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 30

Moving on to step 6:
30 goes into 130 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 30414.0
Deduct 120 from 130 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 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 30414.3
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 30414.33
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 30414.33 and a remainder of 0.01.
