717558 ÷ 78 
Let's see how many times 78 fits into 717558.

Advancing to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 78

Moving on to step 2:
When dividing 71 by 78, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 78

On to step 3:
78 can be fit into 717 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 702 away from 717, we end up with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 78

Let's proceed to step 4:
78 goes into 155 1 times with a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 77 after subtracting 78 from 155.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 78

Moving on to step 5:
The number 78 fits into 775 9 times, leaving a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 919.0
If we take 702 away from 775, we end up with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 78

Step 6:
If we divide 738 by 78, we get 9 and a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 9199.0
Subtracting 702 from 738 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
If we divide 360 by 78, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 9199.4
If we take 312 away from 360, we end up 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.

Let's proceed to step 8:
480 divided by 78 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9199.46
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.

Step 9:
If we divide 120 by 78, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 9199.461
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 78 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9199.4615
Deduct 390 from 420 and we're left 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.

Step 11:
When dividing 300 by 78, we get 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 9199.46153
If we subtract 234 from 300, we 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.

Step 12:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9199.461538
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.

Advancing to step 13:
If we divide 360 by 78, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 9199.4615384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 9199.46153846
Deduct 468 from 480 and we're left 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.

The final outcome is 9199.46153846, with a leftover of 1.2e-08.
