We look at the division of 305729 by 25 
Let's see how many times 25 fits into 305729.

Step 1:
3 divided by 25 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 25

Going ahead to step 2:
30 divided by 25 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 25 from 30 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 25

Advancing to step 3:
55 divided by 25 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 50 from 55 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 25

On to step 4:
25 goes into 57 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 122.0
If we subtract 50 from 57, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 25

Step 5:
The number 25 fits into 72 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1222.0
If we subtract 50 from 72, we get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 25

On to step 6:
229 divided by 25 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 12229.0
The remainder is 4 after subtracting 225 from 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 25 fits into 40 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 12229.1
Subtract 25 from 40 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
25 goes into 150 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 12229.16
If we subtract 150 from 150, 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 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12229.16
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.

Moving on to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12229.16
Subtracting 0 from 0 leaves us 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.

Our division results in 12229.16 with a remaining 0.0.
