Let's divide 489978 by 86
Our goal is to divide 489978 by 86.

Moving on to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 86

Going ahead to step 2:
86 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 86

Going ahead to step 3:
86 goes into 489 5 times with a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 430 away from 489, we end up with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 86

Step 4:
If we divide 599 by 86, we get 6 and a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 83 after subtracting 516 from 599.
Fetch the next digit (7) from the dividend, attach it to 83 and continue: 837 / 86

Advancing to step 5:
86 can be fit into 837 9 times, resulting in a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 569.0
The remainder is 63 after subtracting 774 from 837.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 86

Let's proceed to step 6:
The number 86 fits into 638 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 5697.0
The remainder is 36 after subtracting 602 from 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 5697.4
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.

Moving on to step 8:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 5697.41
Subtract 86 from 160 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
86 can be fit into 740 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 5697.418
The remainder is 52 after subtracting 688 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
520 divided by 86 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 5697.4186
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
86 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5697.4186
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
86 goes into 400 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 5697.418604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
560 divided by 86 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 5697.4186046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5697.41860465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 5697.41860465 and a remainder of 1e-08.
