Let's divide 570339 by 86
Let's see how many times 86 fits into 570339.

On to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 86

Advancing to step 2:
If we divide 57 by 86, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 86

On to step 3:
If we divide 570 by 86, we get 6 and a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 516 away from 570, we end up with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 86

Advancing to step 4:
The number 86 fits into 543 6 times, leaving a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 516 from 543, we get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 86

Going ahead to step 5:
The number 86 fits into 273 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 663.0
If we take 258 away from 273, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 86

On to step 6:
The number 86 fits into 159 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 6631.0
The remainder is 73 after subtracting 86 from 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
86 can be fit into 730 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 6631.8
If we subtract 688 from 730, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 6631.84
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
86 can be fit into 760 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 6631.848
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
720 divided by 86 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6631.8488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 6631.8488, and the remainder is 0.00032.
