We look at the division of 342301 by 30 
We want to divide 342301 by 30.

Step 1:
30 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 30

Step 2:
The number 30 fits into 34 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 30 from 34.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 30

Going ahead to step 3:
42 divided by 30 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 30 from 42 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 30

Advancing to step 4:
If we divide 123 by 30, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtracting 120 from 123 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 30

Moving on to step 5:
The number 30 fits into 30 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1141.0
If we take 30 away from 30, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 30

On to step 6:
30 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 11410.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11410.0
Subtract 0 from 10 to 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.

Moving on to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 11410.03
Subtract 90 from 100 to 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.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 11410.033
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.

The final result is 11410.033 with a remainder of 0.001.
