We're dividing 142025 by 30 
Our goal is to divide 142025 by 30.

Going ahead to step 1:
30 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 30

Step 2:
14 divided by 30 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 30

Step 3:
If we divide 142 by 30, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 120 from 142 to get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 30

Advancing to step 4:
When dividing 220 by 30, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 210 from 220 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 30

Advancing to step 5:
When dividing 102 by 30, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 473.0
If we subtract 90 from 102, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 30

Advancing to step 6:
30 goes into 125 4 times with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4734.0
Deduct 120 from 125 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
30 goes into 50 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 4734.1
The remainder is 20 after subtracting 30 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 4734.16
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 4734.166
Subtracting 180 from 200 leaves us 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.

In conclusion, the division gives 4734.166 with a balance of 0.002.
