486560 ÷ 86 
Our goal is to divide 486560 by 86.

Step 1:
86 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 86

Let's proceed to step 2:
The number 86 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 86

Let's proceed to step 3:
When dividing 486 by 86, we get 5 with a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 430 from 486 and we're left with 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 86

Moving on to step 4:
The number 86 fits into 565 6 times, leaving a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 56.0
The remainder is 49 after subtracting 516 from 565.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 86

Let's proceed to step 5:
If we divide 496 by 86, we get 5 and a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 565.0
The remainder is 66 after subtracting 430 from 496.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 86

Moving on 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: 5657.0
Subtract 602 from 660 to 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.

Let's proceed to step 7:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5657.6
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 5657.67
Subtracting 602 from 640 leaves us 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.

Step 9:
When dividing 380 by 86, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 5657.674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 86 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5657.6744
Subtracting 344 from 360 leaves us with 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 outcome is 5657.6744, with a leftover of 0.00016.
