572191 ÷ 45 
We want to divide 572191 by 45.

Advancing to step 1:
45 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 45

Let's proceed to step 2:
When dividing 57 by 45, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 57 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 45

Step 3:
122 divided by 45 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 90 from 122, we get 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 45

On to step 4:
45 goes into 321 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtracting 315 from 321 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 45

Step 5:
The number 45 fits into 69 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 1271.0
Deduct 45 from 69 and we're left with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 45

Advancing to step 6:
If we divide 241 by 45, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 12715.0
If we subtract 225 from 241, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 45 fits into 160 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 12715.3
Deduct 135 from 160 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 8:
45 goes into 250 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 12715.35
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.

Going ahead to step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 12715.355
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.

Our division results in 12715.355 with a remaining 0.0025.
