360503 divided by 30 
We want to figure out the number of times 360503 can be divided by 30.

Moving on to step 1:
3 divided by 30 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 30

On to step 2:
30 can be fit into 36 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 36 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 30

On to step 3:
60 divided by 30 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 60 from 60 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 30

Moving on to step 4:
5 divided by 30 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 120.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 30

Advancing to step 5:
When dividing 50 by 30, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1201.0
If we subtract 30 from 50, we get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 30

Moving on to step 6:
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: 12016.0
The remainder is 23 after subtracting 180 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
230 divided by 30 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 12016.7
Subtract 210 from 230 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.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 12016.76
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.

Step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 12016.766
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.

The final result is 12016.766 with a remainder of 0.002.
