We're dividing 13112839 by 302 
Our goal is to divide 13112839 by 302.

Let's proceed to step 1:
If we divide 1 by 302, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 302

Step 2:
When dividing 13 by 302, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 302

Moving on to step 3:
302 goes into 131 0 times with a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 131, we end up with 131.
Fetch the next digit (1) from the dividend, attach it to 131 and continue: 1311 / 302

Let's proceed to step 4:
When dividing 1311 by 302, we get 4 with a remainder of 103.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1208 from 1311 and we're left with 103.
Bring next digit (2) of the dividend behind the 103 and repeat the process: 1032 / 302

Step 5:
If we divide 1032 by 302, we get 3 and a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 906 from 1032 to get 126.
Append the next digit (8) from the dividend to 126 and continue with: 1268 / 302

Step 6:
302 goes into 1268 4 times with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 434.0
Subtracting 1208 from 1268 leaves us with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 302

On to step 7:
If we divide 603 by 302, we get 1 and a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 4341.0
Deduct 302 from 603 and we're left with 301.
Take the next digit (9) from the dividend and append it to 301, then repeat: 3019 / 302

On to step 8:
When dividing 3019 by 302, we get 9 with a remainder of 301.
The next digit of our result is 9. 
Result so far: 43419.0
The remainder is 301 after subtracting 2718 from 3019.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 9:
3010 divided by 302 is 9 with a remainder of 292.
Write down 9 as next digit of the result. 
Result so far: 43419.9
Subtracting 2718 from 3010 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 10:
302 goes into 2920 9 times with a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 43419.99
If we take 2718 away from 2920, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final outcome is 43419.99, with a leftover of 0.202.
