258239 divided by 30 
We want to figure out the number of times 258239 can be divided by 30.

Advancing to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 30

Let's proceed to step 2:
If we divide 25 by 30, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 30

On to step 3:
30 can be fit into 258 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 240 from 258 leaves us with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 30

Moving on to step 4:
When dividing 182 by 30, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 180 from 182 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 30

Moving on to step 5:
23 divided by 30 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 860.0
Subtract 0 from 23 to get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 30

Let's proceed to step 6:
If we divide 239 by 30, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 8607.0
The remainder is 29 after subtracting 210 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 8607.9
If we subtract 270 from 290, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 8607.96
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:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 8607.966
If we subtract 180 from 200, we get 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 8607.966 with a balance of 0.002.
