Let's divide 5107225 by 78
Let's see how many times 78 fits into 5107225.

Moving on to step 1:
When dividing 5 by 78, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 78

Going ahead to step 2:
If we divide 51 by 78, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 78

Step 3:
When dividing 510 by 78, we get 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 468 from 510 and we're left with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 78

On to step 4:
If we divide 427 by 78, we get 5 and a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtract 390 from 427 to get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 78

Step 5:
If we divide 372 by 78, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 654.0
If we subtract 312 from 372, we get 60.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 78

Advancing to step 6:
78 goes into 602 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 6547.0
If we subtract 546 from 602, we get 56.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 78

Going ahead to step 7:
If we divide 565 by 78, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 65477.0
If we take 546 away from 565, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
The number 78 fits into 190 2 times, leaving a remainder of 34.
The next digit of our result is 2. 
Result so far: 65477.2
Deduct 156 from 190 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.

Going ahead to step 9:
If we divide 340 by 78, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 65477.24
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 65477.243
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
78 goes into 460 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 65477.2435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
78 can be fit into 700 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 65477.24358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
If we divide 760 by 78, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 65477.243589
The remainder is 58 after subtracting 702 from 760.
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:
If we divide 580 by 78, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 65477.2435897
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 15:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 65477.24358974
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.

In conclusion, the division gives 65477.24358974 with a balance of 2.8e-08.
