We look at the division of 666606 by 25 
Let's see how many times 25 fits into 666606.

Let's proceed to step 1:
25 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 25

Step 2:
25 goes into 66 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 50 from 66, we get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 25

Going ahead to step 3:
25 goes into 166 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 150 from 166 and we're left with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 25

Step 4:
When dividing 166 by 25, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 266.0
The remainder is 16 after subtracting 150 from 166.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 25

Going ahead to step 5:
The number 25 fits into 160 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 2666.0
Deduct 150 from 160 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 25

Moving on to step 6:
25 goes into 106 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 26664.0
If we subtract 100 from 106, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 25, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 26664.2
Deduct 50 from 60 and we're left 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.

Going ahead to step 8:
100 divided by 25 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 26664.24
The remainder is 0 after subtracting 100 from 100.
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.
The next digit of our result is 0. 
Result so far: 26664.24
Subtract 0 from 0 to 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:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26664.24
Subtract 0 from 0 to 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.

Our division results in 26664.24 with a remaining 0.0.
