Let's divide 287670 by 90
Let's see how many times 90 fits into 287670.

Let's proceed to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 90

On to step 2:
If we divide 28 by 90, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 90

On to step 3:
90 goes into 287 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 270 from 287 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 90

Going ahead to step 4:
176 divided by 90 is 1 with a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 86 after subtracting 90 from 176.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 90

Moving on to step 5:
90 can be fit into 867 9 times, resulting in a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 319.0
The remainder is 57 after subtracting 810 from 867.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 90

On to step 6:
570 divided by 90 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 3196.0
Deduct 540 from 570 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 90, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 3196.3
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 90 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3196.33
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 3196.33 with a remaining 0.03.
