We're dividing 960172 by 78 
Let's see how many times 78 fits into 960172.

Going ahead to step 1:
9 divided by 78 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 78

Advancing to step 2:
When dividing 96 by 78, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 78 from 96, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 78

On to step 3:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 156 away from 180, we end up with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 78

On to step 4:
If we divide 241 by 78, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 123.0
Deduct 234 from 241 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 78

Let's proceed to step 5:
78 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 1230.0
If we take 0 away from 77, we end up with 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 78

Advancing to step 6:
The number 78 fits into 772 9 times, leaving a remainder of 70.
The next digit of our result is 9. 
Result so far: 12309.0
If we subtract 702 from 772, we 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.

Going ahead to step 7:
700 divided by 78 is 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 12309.8
Subtract 624 from 700 to get 76.
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 8:
78 goes into 760 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 12309.89
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.

On to step 9:
If we divide 580 by 78, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 12309.897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 12309.8974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 12309.89743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 12309.897435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
78 goes into 700 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 12309.8974358
Subtract 624 from 700 to get 76.
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 14:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 12309.89743589
Deduct 702 from 760 and we're left 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.

The final outcome is 12309.89743589, with a leftover of 5.8e-08.
