491458 ÷ 85 
We're looking to find how many times 85 goes into 491458.

Step 1:
If we divide 4 by 85, 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.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 85

Let's proceed to step 2:
49 divided by 85 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 85

Step 3:
The number 85 fits into 491 5 times, leaving a remainder of 66.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 425 from 491 leaves us with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 85

Step 4:
When dividing 664 by 85, we get 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtracting 595 from 664 leaves us with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 85

Going ahead to step 5:
The number 85 fits into 695 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 578.0
Subtract 680 from 695 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 85

Let's proceed to step 6:
158 divided by 85 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 5781.0
If we take 85 away from 158, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
When dividing 730 by 85, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 5781.8
The remainder is 50 after subtracting 680 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
85 goes into 500 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 5781.85
Deduct 425 from 500 and we're left with 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:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 5781.858
If we take 680 away from 750, we end up 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.

Advancing 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: 5781.8588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 5781.8588 and a remainder of 0.0002.
