We're dividing 77809426 by 911 
Our goal is to divide 77809426 by 911.

Step 1:
911 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
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 911

Going ahead to step 2:
If we divide 77 by 911, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 911

On to step 3:
911 can be fit into 778 0 times, resulting in a remainder of 778.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 778, we end up with 778.
Include the next digit (0) from the dividend after 778, then repeat: 7780 / 911

Going ahead to step 4:
7780 divided by 911 is 8 with a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7288 from 7780 leaves us with 492.
Take the next digit (9) from the dividend and append it to 492, then repeat: 4929 / 911

Moving on to step 5:
The number 911 fits into 4929 5 times, leaving a remainder of 374.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 4555 from 4929, we get 374.
Take the next digit (4) from the dividend and append it to 374, then repeat: 3744 / 911

On to step 6:
When dividing 3744 by 911, we get 4 with a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 854.0
Subtracting 3644 from 3744 leaves us with 100.
Take the next digit (2) from the dividend and append it to 100, then repeat: 1002 / 911

Step 7:
911 can be fit into 1002 1 times, resulting in a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 8541.0
If we subtract 911 from 1002, we get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 911

On to step 8:
The number 911 fits into 916 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 85411.0
Deduct 911 from 916 and we're left 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.

Advancing to step 9:
911 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 85411.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 911, we get 0 and a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 85411.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 85411.0 with a remainder of 0.5.
