405247 divided by 78 
We're looking to find how many times 78 goes into 405247.

Going ahead to step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 78

Going ahead to step 2:
If we divide 40 by 78, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 78

Advancing to step 3:
78 can be fit into 405 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 390 from 405 and we're left with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 78

Step 4:
If we divide 152 by 78, we get 1 and a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 78 from 152, we get 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 78

Going ahead to step 5:
If we divide 744 by 78, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 519.0
Subtract 702 from 744 to get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 78

Moving on to step 6:
When dividing 427 by 78, we get 5 with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 5195.0
Subtract 390 from 427 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
The number 78 fits into 370 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 5195.4
Subtract 312 from 370 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 5195.47
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 5195.474
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
280 divided by 78 is 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 5195.4743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 5195.47435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
700 divided by 78 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 5195.474358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 5195.4743589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
580 divided by 78 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 5195.47435897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 5195.47435897, with a leftover of 3.4e-08.
