We look at the division of 577397 by 80 
Let's see how many times 80 fits into 577397.

Let's proceed to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 80

Step 2:
57 divided by 80 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 80

Going ahead to step 3:
If we divide 577 by 80, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 17 after subtracting 560 from 577.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 80

Going ahead to step 4:
When dividing 173 by 80, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 160 from 173 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 80

Going ahead to step 5:
80 can be fit into 139 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 721.0
The remainder is 59 after subtracting 80 from 139.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 80

Going ahead to step 6:
597 divided by 80 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 7217.0
If we take 560 away from 597, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
80 can be fit into 370 4 times, resulting in a remainder of 50.
The next digit of our result is 4. 
Result so far: 7217.4
If we subtract 320 from 370, we 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.

Advancing to step 8:
500 divided by 80 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7217.46
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 7217.462
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 7217.4625
The remainder is 0 after subtracting 400 from 400.
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:
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: 7217.4625
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.

Advancing to step 12:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7217.4625
Subtracting 0 from 0 leaves us 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.

Our division results in 7217.4625 with a remaining 0.0.
