We look at the division of 659215 by 78 
Let's see how many times 78 fits into 659215.

Moving on to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 78

Advancing to step 2:
When dividing 65 by 78, we get 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 78

Moving on to step 3:
78 can be fit into 659 8 times, resulting in a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 624 from 659 and we're left with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 78

On to step 4:
78 goes into 352 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 312 from 352 leaves us with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 78

Let's proceed to step 5:
401 divided by 78 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 845.0
If we subtract 390 from 401, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 78

Going ahead to step 6:
115 divided by 78 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 8451.0
Deduct 78 from 115 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed 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: 8451.4
If we take 312 away from 370, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead 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: 8451.47
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
When dividing 340 by 78, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 8451.474
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 8451.4743
Subtract 234 from 280 to 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:
If we divide 460 by 78, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 8451.47435
Subtract 390 from 460 to 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.

Let's proceed to step 12:
If we divide 700 by 78, we get 8 and a remainder of 76.
The next digit of our result is 8. 
Result so far: 8451.474358
The remainder is 76 after subtracting 624 from 700.
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:
When dividing 760 by 78, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 8451.4743589
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
78 goes into 580 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 8451.47435897
Subtracting 546 from 580 leaves us 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.

After the division, we end up with 8451.47435897 and a remainder of 3.4e-08.
