We look at the division of 28303290 by 90 
We want to figure out the number of times 28303290 can be divided by 90.

Let's proceed to step 1:
If we divide 2 by 90, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 90

Advancing to step 2:
90 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 90

Step 3:
If we divide 283 by 90, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 270 from 283 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 90

Let's proceed to step 4:
130 divided by 90 is 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 90 away from 130, we end up with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 90

Let's proceed to step 5:
90 goes into 403 4 times with a remainder of 43.
The next digit of our result is 4. 
Result so far: 314.0
If we subtract 360 from 403, we get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 90

Step 6:
If we divide 432 by 90, we get 4 and a remainder of 72.
The next digit of our result is 4. 
Result so far: 3144.0
Subtract 360 from 432 to get 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 90

On to step 7:
If we divide 729 by 90, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 31448.0
If we subtract 720 from 729, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 90

Moving on to step 8:
90 can be fit into 90 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 314481.0
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 314481.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 90, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 314481.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 314481.0 with a remainder of 0.0.
