We're dividing 878683 by 78 
We want to divide 878683 by 78.

Going ahead to step 1:
78 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 78

Advancing to step 2:
When dividing 87 by 78, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 87 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 78

Going ahead to step 3:
78 goes into 98 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 78 from 98 to get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 78

Going ahead to step 4:
If we divide 206 by 78, we get 2 and a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 156 from 206 leaves us with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 78

Advancing to step 5:
78 can be fit into 508 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
Deduct 468 from 508 and we're left with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 78

Step 6:
78 goes into 403 5 times with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 11265.0
Subtract 390 from 403 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
78 can be fit into 130 1 times, resulting in a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 11265.1
The remainder is 52 after subtracting 78 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
When dividing 520 by 78, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 11265.16
Subtract 468 from 520 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 78 fits into 520 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 11265.166
Deduct 468 from 520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 11265.166, with a leftover of 0.0052.
