787109 ÷ 9 
Let's see how many times 9 fits into 787109.

Step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 9

Let's proceed to step 2:
78 divided by 9 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 72 from 78 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 9

On to step 3:
If we divide 67 by 9, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 87.0
If we take 63 away from 67, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 9

Moving on to step 4:
41 divided by 9 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 874.0
Subtracting 36 from 41 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 9

On to step 5:
9 can be fit into 50 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8745.0
The remainder is 5 after subtracting 45 from 50.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 9

Moving on to step 6:
When dividing 59 by 9, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 87456.0
Subtracting 54 from 59 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 87456.5
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
9 goes into 50 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 87456.55
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 87456.55, with a leftover of 0.005.
