Let's divide 303210 by 3
Our goal is to divide 303210 by 3.

Let's proceed to step 1:
3 goes into 3 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Going ahead to step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

On to step 3:
3 can be fit into 3 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Going ahead to step 4:
3 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1010.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Moving on to step 5:
When dividing 21 by 3, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 10107.0
If we subtract 21 from 21, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

On to step 6:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 101070.0
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.

Going ahead to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 101070.0
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.

Moving on to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 101070.0
If we subtract 0 from 0, we get 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 101070.0 with a balance of 0.0.
