30290 divided by 78 
Let's see how many times 78 fits into 30290.

Let's proceed to step 1:
The number 78 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 78

Moving on to step 2:
The number 78 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 78

Let's proceed to step 3:
The number 78 fits into 302 3 times, leaving a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 234 from 302, we get 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 78

On to step 4:
The number 78 fits into 689 8 times, leaving a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 624 from 689 leaves us with 65.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 78

Advancing to step 5:
The number 78 fits into 650 8 times, leaving a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 388.0
Deduct 624 from 650 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 6:
260 divided by 78 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 388.3
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 78, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 388.33
Deduct 234 from 260 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 388.33 with a balance of 0.026.
