305287 divided by 90 
Our goal is to divide 305287 by 90.

Moving on to step 1:
90 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 90

Moving on to step 2:
90 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 90

Moving on to step 3:
If we divide 305 by 90, we get 3 and a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 270 from 305 to get 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 90

Let's proceed to step 4:
90 can be fit into 352 3 times, resulting in a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 270 away from 352, we end up with 82.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 90

Let's proceed to step 5:
If we divide 828 by 90, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 339.0
If we take 810 away from 828, we end up with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 90

Step 6:
90 can be fit into 187 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 3392.0
Subtracting 180 from 187 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 90, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 3392.0
Subtracting 0 from 70 leaves us 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.

Step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 3392.07
Subtracting 630 from 700 leaves us 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.

Step 9:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 3392.077
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 3392.077 with a remainder of 0.007.
