We're dividing 778644 by 99 
Our goal is to divide 778644 by 99.

Step 1:
99 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 99

Step 2:
When dividing 77 by 99, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 99

Moving on to step 3:
778 divided by 99 is 7 with a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 693 from 778 to get 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 99

Let's proceed to step 4:
856 divided by 99 is 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 792 away from 856, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 99

On to step 5:
99 goes into 644 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 786.0
Subtracting 594 from 644 leaves us with 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 99

Advancing to step 6:
The number 99 fits into 504 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 7865.0
Subtracting 495 from 504 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
99 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 7865.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 8:
99 goes into 900 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 7865.09
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
When dividing 90 by 99, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 7865.09
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
900 divided by 99 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 7865.0909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
If we divide 90 by 99, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 7865.0909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
When dividing 900 by 99, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 7865.090909
Subtracting 891 from 900 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
The number 99 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 7865.090909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 14:
99 can be fit into 900 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 7865.09090909
If we subtract 891 from 900, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 7865.09090909 with a balance of 9e-09.
