380421 divided by 30 
Let's see how many times 30 fits into 380421.

Step 1:
30 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

Let's proceed to 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
If we subtract 30 from 38, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 30

Going ahead to step 3:
80 divided by 30 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 60 from 80, we get 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 30

Advancing to step 4:
30 goes into 204 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 180 from 204 leaves us with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 30

Moving on to step 5:
When dividing 242 by 30, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 1268.0
Subtract 240 from 242 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 30

On to step 6:
30 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 12680.0
Subtracting 0 from 21 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
30 can be fit into 210 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 12680.7
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12680.7
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12680.7
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.

In conclusion, the division gives 12680.7 with a balance of 0.0.
