77789336 divided by 9 
We want to divide 77789336 by 9.

Advancing to step 1:
When dividing 7 by 9, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 9

Moving on to step 2:
When dividing 77 by 9, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 72 from 77 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 9

Advancing to step 3:
57 divided by 9 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 54 from 57 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 9

Advancing to step 4:
If we divide 38 by 9, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 864.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Step 5:
9 goes into 29 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 8643.0
Deduct 27 from 29 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 9

On to step 6:
If we divide 23 by 9, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 86432.0
If we subtract 18 from 23, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 9

Step 7:
If we divide 53 by 9, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 864325.0
If we subtract 45 from 53, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 9

Moving on to step 8:
When dividing 86 by 9, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 8643259.0
The remainder is 5 after subtracting 81 from 86.
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 9:
When dividing 50 by 9, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8643259.5
If we take 45 away from 50, we end up 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.

On to step 10:
9 goes into 50 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8643259.55
If we subtract 45 from 50, we 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.

In conclusion, the division gives 8643259.55 with a balance of 0.005.
