We look at the division of 25717 by 30 
We want to divide 25717 by 30.

Advancing to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 30

Step 2:
The number 30 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 30

Step 3:
When dividing 257 by 30, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 240 from 257 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 30

Advancing to step 4:
30 can be fit into 171 5 times, resulting in a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 150 from 171 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 30

Let's proceed to step 5:
If we divide 217 by 30, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 857.0
If we take 210 away from 217, we end up with 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 6:
30 can be fit into 70 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 857.2
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 857.23
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 857.233
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 857.233 with a remaining 0.001.
