We look at the division of 154243 by 30 
Let's see how many times 30 fits into 154243.

Going ahead to step 1:
If we divide 1 by 30, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 30

On to step 2:
The number 30 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 30

Step 3:
When dividing 154 by 30, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 4 after subtracting 150 from 154.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 30

On to step 4:
30 can be fit into 42 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 30 from 42, we get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 30

Going ahead to step 5:
30 can be fit into 124 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 514.0
Subtract 120 from 124 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 30

Advancing to step 6:
30 can be fit into 43 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 5141.0
Subtracting 30 from 43 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
The number 30 fits into 130 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 5141.4
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 5141.43
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.

Going ahead to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5141.433
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.

In conclusion, the division gives 5141.433 with a balance of 0.001.
