490694 ÷ 86 
We want to figure out the number of times 490694 can be divided by 86.

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.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 86

Going ahead to step 2:
86 goes into 49 0 times with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 86

On to step 3:
If we divide 490 by 86, we get 5 and a remainder of 60.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 430 from 490 leaves us with 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 86

On to step 4:
86 can be fit into 606 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we take 602 away from 606, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 86

Let's proceed to step 5:
86 goes into 49 0 times with a remainder of 49.
The next digit of our result is 0. 
Result so far: 570.0
If we subtract 0 from 49, we get 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 86

On to step 6:
86 can be fit into 494 5 times, resulting in a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 5705.0
The remainder is 64 after subtracting 430 from 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
640 divided by 86 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 5705.7
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 5705.74
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 86, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5705.744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 5705.744 with a remainder of 0.0016.
