We look at the division of 489051 by 86 
We're looking to find how many times 86 goes into 489051.

Going ahead to 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
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 86

Going ahead to step 2:
When dividing 48 by 86, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 86

Advancing to step 3:
86 can be fit into 489 5 times, resulting in a remainder of 59.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 430 from 489, we get 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 86

Going ahead to step 4:
If we divide 590 by 86, we get 6 and a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 516 from 590 and we're left with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 86

Moving on to step 5:
When dividing 745 by 86, we get 8 with a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 568.0
Subtract 688 from 745 to get 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 86

Moving on to step 6:
If we divide 571 by 86, we get 6 and a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 5686.0
The remainder is 55 after subtracting 516 from 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
86 can be fit into 550 6 times, resulting in a remainder of 34.
The next digit of our result is 6. 
Result so far: 5686.6
The remainder is 34 after subtracting 516 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
86 goes into 340 3 times with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 5686.63
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
820 divided by 86 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 5686.639
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
The number 86 fits into 460 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5686.6395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 5686.63953
If we subtract 258 from 300, 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.

Step 12:
When dividing 420 by 86, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 5686.639534
Subtracting 344 from 420 leaves us 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.

Moving on to step 13:
If we divide 760 by 86, we get 8 and a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 5686.6395348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5686.63953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 5686.63953488 with a balance of 3.2e-08.
