We divide 30257 by 78
We're looking to find how many times 78 goes into 30257.

Going ahead to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 78

Let's proceed to step 2:
30 divided by 78 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 78

On to step 3:
If we divide 302 by 78, we get 3 and a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 234 from 302, we get 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 78

Step 4:
The number 78 fits into 685 8 times, leaving a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 624 from 685, we get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 78

On to step 5:
When dividing 617 by 78, we get 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
If we subtract 546 from 617, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 6:
When dividing 710 by 78, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 387.9
If we take 702 away from 710, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 387.91
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 78 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 387.91
Subtracting 0 from 20 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.

Moving on to step 9:
When dividing 200 by 78, we get 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 387.9102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
440 divided by 78 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 387.91025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 387.910256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 387.9102564
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 78, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 387.91025641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 387.91025641 with a balance of 2e-09.
