We look at the division of 685872 by 78 
Let's see how many times 78 fits into 685872.

Step 1:
6 divided by 78 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 78

Let's proceed to step 2:
The number 78 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 78

Going ahead to step 3:
78 can be fit into 685 8 times, resulting in a remainder of 61.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 61 after subtracting 624 from 685.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 78

Going ahead to step 4:
78 goes into 618 7 times with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 546 from 618 and we're left with 72.
Fetch the next digit (7) from the dividend, attach it to 72 and continue: 727 / 78

Let's proceed to step 5:
If we divide 727 by 78, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 879.0
The remainder is 25 after subtracting 702 from 727.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 78

Moving on to step 6:
78 goes into 252 3 times with a remainder of 18.
The next digit of our result is 3. 
Result so far: 8793.0
Subtracting 234 from 252 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 8793.2
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.

Let's proceed to step 8:
78 goes into 240 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 8793.23
Deduct 234 from 240 and we're left 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.

Advancing to step 9:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8793.23
Subtracting 0 from 60 leaves us 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.

Moving on to step 10:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 8793.2307
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 11:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 8793.23076
Deduct 468 from 540 and we're left with 72.
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 12:
720 divided by 78 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 8793.230769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 8793.2307692
If we take 156 away from 180, we end up with 24.
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 14:
78 goes into 240 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 8793.23076923
Subtract 234 from 240 to 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.

Our division results in 8793.23076923 with a remaining 6e-09.
