We look at the division of 518681 by 90 
Let's see how many times 90 fits into 518681.

Advancing to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 90

Advancing to step 2:
If we divide 51 by 90, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 90

Moving on to step 3:
If we divide 518 by 90, we get 5 and a remainder of 68.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 450 from 518 leaves us with 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 90

Let's proceed to step 4:
90 can be fit into 686 7 times, resulting in a remainder of 56.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 630 from 686 to get 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 90

On to step 5:
When dividing 568 by 90, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 576.0
If we subtract 540 from 568, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 90

Let's proceed to step 6:
281 divided by 90 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 5763.0
Subtract 270 from 281 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 90 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 5763.1
If we subtract 90 from 110, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5763.12
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 90 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 5763.122
Deduct 180 from 200 and we're left 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 5763.122 with a remaining 0.002.
