378789 divided by 30 
We want to figure out the number of times 378789 can be divided by 30.

Moving on to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 30

Step 2:
The number 30 fits into 37 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 30 from 37 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 30

On to step 3:
30 goes into 78 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 60 from 78 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 30

Moving on to step 4:
30 can be fit into 187 6 times, resulting in a remainder of 7.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 180 from 187 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 30

Step 5:
30 can be fit into 78 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 1262.0
Deduct 60 from 78 and we're left with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 30

On to step 6:
If we divide 189 by 30, we get 6 and a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 12626.0
The remainder is 9 after subtracting 180 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 30 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 12626.3
Subtracting 90 from 90 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.

Going ahead to step 8:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12626.3
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.

Moving on to step 9:
30 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12626.3
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 12626.3 with a balance of 0.0.
