We look at the division of 200305 by 90 
Let's see how many times 90 fits into 200305.

Step 1:
2 divided by 90 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 90

On to step 2:
90 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 90

On to step 3:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 180 from 200 and we're left with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 90

Let's proceed to step 4:
The number 90 fits into 203 2 times, leaving a remainder of 23.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 180 from 203 to get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 90

Step 5:
The number 90 fits into 230 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 222.0
The remainder is 50 after subtracting 180 from 230.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 90

On to step 6:
505 divided by 90 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 2225.0
The remainder is 55 after subtracting 450 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
90 goes into 550 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 2225.6
If we take 540 away from 550, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 90 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 2225.61
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 90 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 2225.611
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 2225.611 and a remainder of 0.001.
