3394209 ÷ 303 
Let's see how many times 303 fits into 3394209.

Going ahead to step 1:
If we divide 3 by 303, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 303

Let's proceed to step 2:
When dividing 33 by 303, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 303

Step 3:
When dividing 339 by 303, we get 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 303 from 339 to get 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 303

Let's proceed to step 4:
303 can be fit into 364 1 times, resulting in a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 303 from 364 to get 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 303

On to step 5:
The number 303 fits into 612 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we subtract 606 from 612, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 303

Advancing to step 6:
303 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 1120.0
If we take 0 away from 60, we end up with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 303

Let's proceed to step 7:
303 can be fit into 609 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 11202.0
Deduct 606 from 609 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
If we divide 30 by 303, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11202.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 303 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 11202.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 11202.0 with a remaining 0.3.
