We look at the division of 575171 by 45 
We want to figure out the number of times 575171 can be divided by 45.

Let's proceed to step 1:
45 can be fit into 5 0 times, resulting in 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.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 45

Step 2:
45 can be fit into 57 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 45

Step 3:
45 can be fit into 125 2 times, resulting in a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 35 after subtracting 90 from 125.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 45

Let's proceed to step 4:
The number 45 fits into 351 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 127.0
The remainder is 36 after subtracting 315 from 351.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 45

Going ahead to step 5:
If we divide 367 by 45, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 1278.0
The remainder is 7 after subtracting 360 from 367.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 45

Going ahead to step 6:
45 can be fit into 71 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 12781.0
The remainder is 26 after subtracting 45 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
45 can be fit into 260 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 12781.5
Subtracting 225 from 260 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
45 goes into 350 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 12781.57
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 12781.577
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 12781.577, with a leftover of 0.0035.
