456664 ÷ 25 
Let's see how many times 25 fits into 456664.

Moving on to step 1:
If we divide 4 by 25, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 25

Let's proceed to step 2:
When dividing 45 by 25, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 25 from 45 to get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 25

Going ahead to step 3:
25 goes into 206 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 200 away from 206, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 25

Advancing to step 4:
The number 25 fits into 66 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 182.0
Subtracting 50 from 66 leaves us with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 25

Step 5:
25 can be fit into 166 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1826.0
Subtract 150 from 166 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 25

On to step 6:
25 can be fit into 164 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 18266.0
Deduct 150 from 164 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
If we divide 140 by 25, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 18266.5
The remainder is 15 after subtracting 125 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

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: 18266.56
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18266.56
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.

Moving on to step 10:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18266.56
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.

The final outcome is 18266.56, with a leftover of 0.0.
