394320 divided by 78 
Our goal is to divide 394320 by 78.

On to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 78

On to step 2:
39 divided by 78 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 78

Step 3:
78 can be fit into 394 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 390 away from 394, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 78

Let's proceed to step 4:
If we divide 43 by 78, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtract 0 from 43 to get 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 78

Going ahead to step 5:
432 divided by 78 is 5 with a remainder of 42.
The next digit of our result is 5. 
Result so far: 505.0
If we take 390 away from 432, we end up with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 78

Going ahead to step 6:
If we divide 420 by 78, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5055.0
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 5055.3
If we subtract 234 from 300, 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.

Step 8:
78 goes into 660 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 5055.38
If we take 624 away from 660, we end up 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.

Advancing to step 9:
78 can be fit into 360 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 5055.384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
78 goes into 480 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 5055.3846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 5055.38461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
78 goes into 420 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 5055.384615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
300 divided by 78 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 5055.3846153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
If we divide 660 by 78, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 5055.38461538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 5055.38461538 with a remaining 3.6e-08.
