394158 divided by 78 
Let's see how many times 78 fits into 394158.

Moving on to step 1:
3 divided by 78 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 78

Moving on to step 2:
78 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 78

Moving on to step 3:
78 can be fit into 394 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 390 from 394, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 78

On to step 4:
The number 78 fits into 41 0 times, leaving a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 41, we end up with 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 78

Going ahead to step 5:
If we divide 415 by 78, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 505.0
Subtract 390 from 415 to get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 78

Step 6:
258 divided by 78 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 5053.0
The remainder is 24 after subtracting 234 from 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 78, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 5053.3
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 78 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5053.3
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 78 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 5053.307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 78, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 5053.3076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 5053.30769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
If we divide 180 by 78, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 5053.307692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5053.3076923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5053.3076923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 5053.3076923 with a remainder of 6e-08.
