We divide 777939 by 90
Our goal is to divide 777939 by 90.

Going ahead to step 1:
7 divided by 90 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 90

Let's proceed to step 2:
When dividing 77 by 90, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 90

Going ahead to step 3:
If we divide 777 by 90, we get 8 and a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 720 from 777, we get 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 90

Moving on to step 4:
If we divide 579 by 90, we get 6 and a remainder of 39.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 540 from 579 leaves us with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 90

On to step 5:
If we divide 393 by 90, we get 4 and a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 864.0
If we take 360 away from 393, we end up with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 90

Advancing to step 6:
The number 90 fits into 339 3 times, leaving a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 8643.0
If we take 270 away from 339, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
90 goes into 690 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 8643.7
The remainder is 60 after subtracting 630 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 8643.76
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 8643.766
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 8643.766 with a balance of 0.006.
