Let's divide 287180 by 90
Our goal is to divide 287180 by 90.

Advancing to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 90

Moving on to step 2:
28 divided by 90 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 90

Let's proceed to step 3:
287 divided by 90 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 270 from 287 to get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 90

On to step 4:
171 divided by 90 is 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 90 from 171 leaves us with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 90

Going ahead to step 5:
When dividing 818 by 90, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 319.0
Deduct 810 from 818 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 90

Step 6:
When dividing 80 by 90, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 3190.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 7:
If we divide 800 by 90, we get 8 and a remainder of 80.
The next digit of our result is 8. 
Result so far: 3190.8
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 3190.88
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 3190.88 with a remaining 0.08.
