339291 divided by 78 
We want to divide 339291 by 78.

On to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 78

Step 2:
78 goes into 33 0 times with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 78

Going ahead to step 3:
339 divided by 78 is 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 312 from 339, we get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 78

Moving on to step 4:
When dividing 272 by 78, we get 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 234 away from 272, we end up with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 78

Advancing to step 5:
78 goes into 389 4 times with a remainder of 77.
The next digit of our result is 4. 
Result so far: 434.0
Subtract 312 from 389 to get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 78

Moving on to step 6:
The number 78 fits into 771 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 4349.0
If we subtract 702 from 771, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
78 can be fit into 690 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 4349.8
If we subtract 624 from 690, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
If we divide 660 by 78, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 4349.88
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 4349.88 with a remainder of 0.036.
