503987 ÷ 330 
Our goal is to divide 503987 by 330.

Moving on to step 1:
The number 330 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 330

On to step 2:
330 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 330

Step 3:
330 goes into 503 1 times with a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 330 from 503 to get 173.
Grab the next digit (9) from the dividend, add it to 173, then carry on: 1739 / 330

Moving on to step 4:
When dividing 1739 by 330, we get 5 with a remainder of 89.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1650 from 1739 leaves us with 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 330

Let's proceed to step 5:
The number 330 fits into 898 2 times, leaving a remainder of 238.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we take 660 away from 898, we end up with 238.
Append the next digit (7) from the dividend to 238 and continue with: 2387 / 330

Let's proceed to step 6:
330 can be fit into 2387 7 times, resulting in a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 1527.0
Subtract 2310 from 2387 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
330 goes into 770 2 times with a remainder of 110.
The next digit of our result is 2. 
Result so far: 1527.2
If we take 660 away from 770, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 8:
330 can be fit into 1100 3 times, resulting in a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 1527.23
The remainder is 110 after subtracting 990 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
If we divide 1100 by 330, we get 3 and a remainder of 110.
Write down 3 as next digit of the result. 
Result so far: 1527.233
If we subtract 990 from 1100, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 1527.233, and the remainder is 0.011.
