512360 divided by 86 
Let's see how many times 86 fits into 512360.

Step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 86

Going ahead to step 2:
The number 86 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 86

Let's proceed to step 3:
86 can be fit into 512 5 times, resulting in a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 430 from 512 leaves us with 82.
Fetch the next digit (3) from the dividend, attach it to 82 and continue: 823 / 86

Advancing to step 4:
The number 86 fits into 823 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we take 774 away from 823, we end up with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 86

Moving on to step 5:
496 divided by 86 is 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 595.0
Deduct 430 from 496 and we're left with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 86

Advancing to step 6:
86 can be fit into 660 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 5957.0
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
580 divided by 86 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 5957.6
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
If we divide 640 by 86, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 5957.67
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
380 divided by 86 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 5957.674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 5957.6744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 5957.6744 with a remainder of 0.00016.
