We're dividing 981579 by 78 
Let's see how many times 78 fits into 981579.

Let's proceed to step 1:
78 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 78

Step 2:
78 goes into 98 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 78 from 98, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 78

Moving on to step 3:
The number 78 fits into 201 2 times, leaving a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 156 from 201 and we're left with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 78

Let's proceed to step 4:
455 divided by 78 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 390 from 455 leaves us with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 78

On to step 5:
78 can be fit into 657 8 times, resulting in a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 1258.0
If we subtract 624 from 657, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 78

Step 6:
78 can be fit into 339 4 times, resulting in a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 12584.0
Subtract 312 from 339 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 78, we get 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 12584.3
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 12584.34
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 78, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 12584.346
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 78, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 12584.3461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
420 divided by 78 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 12584.34615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
If we divide 300 by 78, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 12584.346153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 12584.3461538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
78 goes into 360 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 12584.34615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 12584.34615384, with a leftover of 4.8e-08.
