871004 divided by 57 
We want to figure out the number of times 871004 can be divided by 57.

Going ahead to step 1:
8 divided by 57 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 57

Let's proceed to step 2:
57 goes into 87 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 57 from 87 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 57

Going ahead to step 3:
57 goes into 301 5 times with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 285 away from 301, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 57

Moving on to step 4:
57 goes into 160 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
If we subtract 114 from 160, we get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 57

Moving on to step 5:
If we divide 460 by 57, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1528.0
Subtracting 456 from 460 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 57

Let's proceed to step 6:
The number 57 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 15280.0
The remainder is 44 after subtracting 0 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
If we divide 440 by 57, we get 7 and a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 15280.7
Deduct 399 from 440 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
410 divided by 57 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 15280.77
Subtracting 399 from 410 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 15280.77, and the remainder is 0.011.
