We're dividing 303107 by 30 
Our goal is to divide 303107 by 30.

Moving on to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 30

Step 2:
30 divided by 30 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 30 from 30 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 30

Going ahead to step 3:
When dividing 3 by 30, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 30

Step 4:
The number 30 fits into 31 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 30 from 31 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 30

Moving on to step 5:
30 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1010.0
Subtract 0 from 10 to get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 30

Step 6:
107 divided by 30 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 10103.0
If we take 90 away from 107, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 30 fits into 170 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 10103.5
If we subtract 150 from 170, 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 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 10103.56
If we take 180 away from 200, we end up 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 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 10103.566
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.

Our division results in 10103.566 with a remaining 0.002.
