We divide 603831 by 30
Our goal is to divide 603831 by 30.

Advancing to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 30

On to step 2:
The number 30 fits into 60 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 60 from 60.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 30

Moving on to step 3:
30 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

On to step 4:
38 divided by 30 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 201.0
Deduct 30 from 38 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 30

Step 5:
The number 30 fits into 83 2 times, leaving a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2012.0
The remainder is 23 after subtracting 60 from 83.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 30

Moving on to step 6:
When dividing 231 by 30, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 20127.0
If we take 210 away from 231, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
30 goes into 210 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 20127.7
If we take 210 away from 210, 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.

Let's proceed to step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20127.7
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.

Going ahead to step 9:
30 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20127.7
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.

The final outcome is 20127.7, with a leftover of 0.0.
