577727 divided by 80 
Let's see how many times 80 fits into 577727.

Let's proceed to step 1:
5 divided by 80 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 80

Going ahead to step 2:
If we divide 57 by 80, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 80

Moving on to step 3:
80 can be fit into 577 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 560 from 577, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 80

Advancing to step 4:
177 divided by 80 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we subtract 160 from 177, we get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 80

Going ahead to step 5:
If we divide 172 by 80, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 722.0
Subtracting 160 from 172 leaves us with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 80

Going ahead to step 6:
80 goes into 127 1 times with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 7221.0
If we take 80 away from 127, we end up with 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 7:
80 can be fit into 470 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7221.5
Subtract 400 from 470 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 7221.58
Deduct 640 from 700 and we're left 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.

Advancing to step 9:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 7221.587
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.

Moving on to step 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7221.5875
If we subtract 400 from 400, 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.

Going ahead to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7221.5875
Deduct 0 from 0 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 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7221.5875
Deduct 0 from 0 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.

After the division, we end up with 7221.5875 and a remainder of 0.0.
