Let's divide 17903 by 30
We're looking to find how many times 30 goes into 17903.

Let's proceed to step 1:
1 divided by 30 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 30

Let's proceed to step 2:
When dividing 17 by 30, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 30

On to step 3:
The number 30 fits into 179 5 times, leaving a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 150 from 179 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 30

Step 4:
30 can be fit into 290 9 times, resulting in a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 270 from 290 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 30

Going ahead to step 5:
30 can be fit into 203 6 times, resulting in a remainder of 23.
The next digit of our result is 6. 
Result so far: 596.0
Subtract 180 from 203 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 6:
The number 30 fits into 230 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 596.7
Subtracting 210 from 230 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.

Going ahead to step 7:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 596.76
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.

Moving on to step 8:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 596.766
Subtract 180 from 200 to 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 596.766 with a balance of 0.002.
