530438 divided by 30 
Our goal is to divide 530438 by 30.

On to step 1:
30 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 30

Advancing to step 2:
The number 30 fits into 53 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 30 from 53 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 30

Advancing to step 3:
30 can be fit into 230 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 210 from 230 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 30

Step 4:
When dividing 204 by 30, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
Deduct 180 from 204 and we're left with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 30

Step 5:
If we divide 243 by 30, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 1768.0
Subtract 240 from 243 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 30

On to step 6:
38 divided by 30 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 17681.0
The remainder is 8 after subtracting 30 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
30 goes into 80 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 17681.2
The remainder is 20 after subtracting 60 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 17681.26
Deduct 180 from 200 and we're left 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.

Step 9:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 17681.266
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 17681.266 with a balance of 0.002.
