We look at the division of 223393 by 45 
Let's see how many times 45 fits into 223393.

Step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 45

Moving on to step 2:
22 divided by 45 is 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 45

Going ahead to step 3:
223 divided by 45 is 4 with a remainder of 43.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 180 from 223 leaves us with 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 45

Let's proceed to step 4:
433 divided by 45 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 405 away from 433, we end up with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 45

Step 5:
45 goes into 289 6 times with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
Subtract 270 from 289 to get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 45

Advancing to step 6:
If we divide 193 by 45, we get 4 and a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4964.0
If we take 180 away from 193, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 45, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 4964.2
Subtracting 90 from 130 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 4964.28
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 4964.288
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 4964.288 with a remaining 0.004.
