577654 ÷ 80 
Let's see how many times 80 fits into 577654.

Advancing to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 80

Going ahead to step 2:
80 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 80

Step 3:
When dividing 577 by 80, we get 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 17 after subtracting 560 from 577.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 80

Let's proceed to step 4:
When dividing 176 by 80, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 72.0
The remainder is 16 after subtracting 160 from 176.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 80

Step 5:
If we divide 165 by 80, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 722.0
If we subtract 160 from 165, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 80

On to step 6:
When dividing 54 by 80, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 7220.0
Subtracting 0 from 54 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
When dividing 540 by 80, we get 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 7220.6
Subtracting 480 from 540 leaves us 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.

Step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7220.67
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 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 7220.675
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 7220.675
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.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7220.675
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7220.675, and the remainder is 0.0.
