We look at the division of 491917 by 85 
We want to figure out the number of times 491917 can be divided by 85.

Step 1:
4 divided by 85 is 0 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.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 85

Moving on to step 2:
The number 85 fits into 49 0 times, leaving a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 85

Moving on to step 3:
When dividing 491 by 85, we get 5 with a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 425 from 491 leaves us with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 85

Advancing to step 4:
If we divide 669 by 85, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 74 after subtracting 595 from 669.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 85

Let's proceed to step 5:
If we divide 741 by 85, we get 8 and a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 578.0
If we subtract 680 from 741, we get 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 85

Advancing to step 6:
When dividing 617 by 85, we get 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 5787.0
Subtract 595 from 617 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 85, we get 2 and a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 5787.2
If we take 170 away from 220, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 85 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 5787.25
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
The next digit of our result is 8. 
Result so far: 5787.258
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
85 goes into 700 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 5787.2588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 5787.2588 with a remaining 0.0002.
