We look at the division of 65990 by 25 
Let's see how many times 25 fits into 65990.

On to step 1:
25 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 25

Advancing to step 2:
65 divided by 25 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 15 after subtracting 50 from 65.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 25

Moving on to step 3:
The number 25 fits into 159 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 150 from 159, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 25

Moving on to step 4:
99 divided by 25 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Subtract 75 from 99 to get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 25

Advancing to step 5:
240 divided by 25 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 2639.0
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 6:
25 goes into 150 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2639.6
Subtract 150 from 150 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.

Step 7:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2639.6
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.

Going ahead to step 8:
25 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2639.6
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.

The quotient of the division is 2639.6, and the remainder is 0.0.
