We look at the division of 803573 by 25 
We're looking to find how many times 25 goes into 803573.

Moving on to step 1:
The number 25 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 25

Step 2:
The number 25 fits into 80 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 75 from 80 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 25

Moving on to step 3:
53 divided by 25 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 50 from 53 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 25

Moving on to step 4:
25 can be fit into 35 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 321.0
The remainder is 10 after subtracting 25 from 35.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 25

Step 5:
The number 25 fits into 107 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 3214.0
The remainder is 7 after subtracting 100 from 107.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 25

Advancing to step 6:
If we divide 73 by 25, we get 2 and a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 32142.0
Deduct 50 from 73 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
25 goes into 230 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 32142.9
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 32142.92
If we subtract 50 from 50, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32142.92
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32142.92
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 32142.92 with a remainder of 0.0.
