We're dividing 77695563 by 855 
Our goal is to divide 77695563 by 855.

Step 1:
If we divide 7 by 855, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 855

On to step 2:
When dividing 77 by 855, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 855

Advancing to step 3:
855 can be fit into 776 0 times, resulting in a remainder of 776.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 776 and we're left with 776.
Grab the next digit (9) from the dividend, add it to 776, then carry on: 7769 / 855

Moving on to step 4:
The number 855 fits into 7769 9 times, leaving a remainder of 74.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 74 after subtracting 7695 from 7769.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 855

Moving on to step 5:
When dividing 745 by 855, we get 0 with a remainder of 745.
The next digit of our result is 0. 
Result so far: 90.0
The remainder is 745 after subtracting 0 from 745.
Fetch the next digit (5) from the dividend, attach it to 745 and continue: 7455 / 855

On to step 6:
The number 855 fits into 7455 8 times, leaving a remainder of 615.
Record the quotient 8 as the next digit in the result. 
Result so far: 908.0
The remainder is 615 after subtracting 6840 from 7455.
Grab the next digit (6) from the dividend, add it to 615, then carry on: 6156 / 855

Step 7:
If we divide 6156 by 855, we get 7 and a remainder of 171.
The number 7 becomes the next digit in our result. 
Result so far: 9087.0
Subtract 5985 from 6156 to get 171.
Include the next digit (3) from the dividend after 171, then repeat: 1713 / 855

Moving on to step 8:
1713 divided by 855 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 90872.0
Subtract 1710 from 1713 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 855, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 90872.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 855, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 90872.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 90872.0 with a remaining 0.3.
