645748 divided by 25 
Let's see how many times 25 fits into 645748.

On to step 1:
25 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 25

Going ahead to step 2:
64 divided by 25 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 50 from 64 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 25

Step 3:
145 divided by 25 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 125 from 145 to get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 25

Moving on to step 4:
207 divided by 25 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 258.0
Subtract 200 from 207 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 25

Going ahead to step 5:
The number 25 fits into 74 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2582.0
Subtract 50 from 74 to get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 25

Moving on to step 6:
If we divide 248 by 25, we get 9 and a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 25829.0
If we take 225 away from 248, we end up 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.

Going ahead to step 7:
When dividing 230 by 25, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 25829.9
If we subtract 225 from 230, we get 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: 25829.92
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:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25829.92
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 25829.92
The remainder is 0 after subtracting 0 from 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 25829.92 with a remaining 0.0.
