We look at the division of 489173 by 86 
We want to divide 489173 by 86.

Moving on to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 86

Step 2:
86 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 86

Going ahead to step 3:
The number 86 fits into 489 5 times, leaving a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 430 from 489 leaves us with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 86

Step 4:
The number 86 fits into 591 6 times, leaving a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we take 516 away from 591, we end up with 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 86

On to step 5:
86 goes into 757 8 times with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 568.0
Subtract 688 from 757 to get 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 86

Moving on to step 6:
693 divided by 86 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 5688.0
If we take 688 away from 693, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 86, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5688.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
86 goes into 500 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 5688.05
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
86 goes into 700 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 5688.058
The remainder is 12 after subtracting 688 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
86 goes into 120 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 5688.0581
The remainder is 34 after subtracting 86 from 120.
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 11:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 5688.05813
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.

Advancing to step 12:
820 divided by 86 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 5688.058139
Deduct 774 from 820 and we're left 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.

Going ahead to step 13:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5688.0581395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
86 goes into 300 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 5688.05813953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 5688.05813953, and the remainder is 4.2e-08.
