380429 ÷ 30 
We want to figure out the number of times 380429 can be divided by 30.

Going ahead to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 30

Step 2:
30 goes into 38 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 30 from 38 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 30

Advancing to step 3:
30 goes into 80 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 60 from 80, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 30

Let's proceed to step 4:
When dividing 204 by 30, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtract 180 from 204 to get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 30

Step 5:
The number 30 fits into 242 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1268.0
Deduct 240 from 242 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 30

Advancing to step 6:
The number 30 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 12680.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
30 goes into 290 9 times with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 12680.9
Deduct 270 from 290 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.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 12680.96
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.

Moving on to step 9:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 12680.966
Subtracting 180 from 200 leaves us 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.

The final result is 12680.966 with a remainder of 0.002.
