We divide 872557 by 45
Our goal is to divide 872557 by 45.

Moving on to step 1:
8 divided by 45 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 45

Moving on to step 2:
87 divided by 45 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 87 and we're left with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 45

Advancing to step 3:
422 divided by 45 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 17 after subtracting 405 from 422.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 45

Moving on to step 4:
45 can be fit into 175 3 times, resulting in a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 193.0
Subtract 135 from 175 to get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 45

Advancing to step 5:
45 goes into 405 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 1939.0
Subtract 405 from 405 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 45

Advancing to step 6:
If we divide 7 by 45, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 19390.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 45, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 19390.1
Subtract 45 from 70 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
250 divided by 45 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 19390.15
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:
250 divided by 45 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 19390.155
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.

The final outcome is 19390.155, with a leftover of 0.0025.
