We divide 573171 by 77
We want to divide 573171 by 77.

Going ahead to step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 77

Moving on to step 2:
57 divided by 77 is 0 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 (3) of the dividend behind the 57 and repeat the process: 573 / 77

On to step 3:
77 can be fit into 573 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 539 from 573, we get 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 77

Step 4:
When dividing 341 by 77, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 308 from 341, we get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 77

Moving on to step 5:
If we divide 337 by 77, we get 4 and a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 744.0
Subtract 308 from 337 to get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 77

Let's proceed to step 6:
If we divide 291 by 77, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 7443.0
The remainder is 60 after subtracting 231 from 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 7443.7
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
77 goes into 610 7 times with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 7443.77
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 7443.77, and the remainder is 0.071.
