We look at the division of 200473 by 45 
We want to figure out the number of times 200473 can be divided by 45.

Advancing to step 1:
45 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

Advancing to step 2:
20 divided by 45 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 45

Going ahead to step 3:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 180 from 200 and we're left with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 45

Moving on to step 4:
204 divided by 45 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 180 from 204 to get 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 45

Advancing to step 5:
45 goes into 247 5 times with a remainder of 22.
The next digit of our result is 5. 
Result so far: 445.0
Subtract 225 from 247 to get 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 45

On to step 6:
45 can be fit into 223 4 times, resulting in a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 4454.0
Subtracting 180 from 223 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
45 goes into 430 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 4454.9
Subtracting 405 from 430 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.

Going ahead to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4454.95
The remainder is 25 after subtracting 225 from 250.
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 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4454.955
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.

The final result is 4454.955 with a remainder of 0.0025.
