We're dividing 860071 by 78 
Let's see how many times 78 fits into 860071.

Let's proceed to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 78

Step 2:
If we divide 86 by 78, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 8 after subtracting 78 from 86.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 78

Going ahead to step 3:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 78 from 80 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 78

Moving on to step 4:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we take 0 away from 20, we end up with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 78

Moving on to step 5:
78 can be fit into 207 2 times, resulting in a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 1102.0
If we take 156 away from 207, we end up with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 78

Going ahead to step 6:
511 divided by 78 is 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 11026.0
Subtract 468 from 511 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 78 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 11026.5
The remainder is 40 after subtracting 390 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11026.55
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 11026.55, with a leftover of 0.01.
