Let's divide 903387 by 30
We want to figure out the number of times 903387 can be divided by 30.

Step 1:
9 divided by 30 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 30

On to step 2:
When dividing 90 by 30, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 30

Moving on to step 3:
If we divide 3 by 30, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 3 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 30

Step 4:
The number 30 fits into 33 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 301.0
Subtract 30 from 33 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

On to step 5:
30 goes into 38 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 3011.0
If we take 30 away from 38, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 30

Advancing to step 6:
When dividing 87 by 30, we get 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 30112.0
If we take 60 away from 87, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 30, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 30112.9
Subtracting 270 from 270 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 30 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30112.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30112.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 30112.9 with a balance of 0.0.
