Let's divide 77287 by 9
Our goal is to divide 77287 by 9.

Advancing to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 9

Let's proceed to step 2:
9 can be fit into 77 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 72 away from 77, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 9

Step 3:
9 goes into 52 5 times with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 85.0
The remainder is 7 after subtracting 45 from 52.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 9

Advancing to step 4:
78 divided by 9 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 858.0
Subtract 72 from 78 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 9

Step 5:
If we divide 67 by 9, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 8587.0
Deduct 63 from 67 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 6:
When dividing 40 by 9, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 8587.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 8587.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 8587.44 with a remainder of 0.004.
