We look at the division of 660946 by 25 
We want to divide 660946 by 25.

Let's proceed to step 1:
If we divide 6 by 25, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 25

Advancing to step 2:
When dividing 66 by 25, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
If we take 50 away from 66, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 25

Going ahead to step 3:
The number 25 fits into 160 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 150 from 160 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 25

Advancing to step 4:
The number 25 fits into 109 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 264.0
Deduct 100 from 109 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 25

Advancing to step 5:
If we divide 94 by 25, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 2643.0
Subtract 75 from 94 to get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 25

Step 6:
If we divide 196 by 25, we get 7 and a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 26437.0
The remainder is 21 after subtracting 175 from 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 25 fits into 210 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 26437.8
If we subtract 200 from 210, we 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.

On to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 26437.84
If we take 100 away from 100, we end up 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.

Going ahead to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26437.84
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.

Advancing to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26437.84
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.

The final result is 26437.84 with a remainder of 0.0.
