We're dividing 77807 by 80 
Let's see how many times 80 fits into 77807.

On to step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
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 / 80

Step 2:
The number 80 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 80

Step 3:
The number 80 fits into 778 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 720 from 778 and we're left with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 80

Step 4:
80 can be fit into 580 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Subtracting 560 from 580 leaves us with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 80

On to step 5:
80 can be fit into 207 2 times, resulting in a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
Subtract 160 from 207 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 6:
If we divide 470 by 80, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 972.5
If we take 400 away from 470, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
If we divide 700 by 80, we get 8 and a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 972.58
Subtract 640 from 700 to get 60.
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:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 972.587
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 972.5875
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 972.5875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 972.5875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 972.5875 with a remaining 0.0.
