202300 ÷ 45 
We're looking to find how many times 45 goes into 202300.

Moving on to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 45

Advancing to step 2:
45 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 45

Let's proceed to step 3:
45 can be fit into 202 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 180 from 202 and we're left with 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 45

Let's proceed to step 4:
When dividing 223 by 45, we get 4 with a remainder of 43.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 180 from 223, we get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 45

Let's proceed to step 5:
45 goes into 430 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 449.0
If we take 405 away from 430, we end up with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 45

Let's proceed to step 6:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4495.0
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4495.5
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 4495.55
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 4495.55 with a remainder of 0.025.
