We divide 571239 by 87
We're looking to find how many times 87 goes into 571239.

On to step 1:
If we divide 5 by 87, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 87

Moving on to step 2:
The number 87 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 87

On to step 3:
If we divide 571 by 87, we get 6 and a remainder of 49.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 522 from 571 to get 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 87

On to step 4:
87 goes into 492 5 times with a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 65.0
The remainder is 57 after subtracting 435 from 492.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 87

Moving on to step 5:
87 goes into 573 6 times with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 656.0
If we subtract 522 from 573, we get 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 87

On to step 6:
The number 87 fits into 519 5 times, leaving a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 6565.0
Deduct 435 from 519 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 7:
When dividing 840 by 87, we get 9 with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 6565.9
If we subtract 783 from 840, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 8:
If we divide 570 by 87, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 6565.96
Subtracting 522 from 570 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 87, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 6565.965
If we subtract 435 from 480, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
When dividing 450 by 87, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6565.9655
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 6565.9655 and a remainder of 0.00015.
