640025 divided by 240 
We want to figure out the number of times 640025 can be divided by 240.

On to step 1:
When dividing 6 by 240, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 240

Moving on to step 2:
240 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 240

On to step 3:
240 can be fit into 640 2 times, resulting in a remainder of 160.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 160 after subtracting 480 from 640.
Fetch the next digit (0) from the dividend, attach it to 160 and continue: 1600 / 240

Step 4:
If we divide 1600 by 240, we get 6 and a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 160 after subtracting 1440 from 1600.
Fetch the next digit (2) from the dividend, attach it to 160 and continue: 1602 / 240

Let's proceed to step 5:
The number 240 fits into 1602 6 times, leaving a remainder of 162.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
Subtract 1440 from 1602 to get 162.
Fetch the next digit (5) from the dividend, attach it to 162 and continue: 1625 / 240

Going ahead to step 6:
If we divide 1625 by 240, we get 6 and a remainder of 185.
The number 6 becomes the next digit in our result. 
Result so far: 2666.0
The remainder is 185 after subtracting 1440 from 1625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 7:
The number 240 fits into 1850 7 times, leaving a remainder of 170.
Record the quotient 7 as the next digit in the result. 
Result so far: 2666.7
If we subtract 1680 from 1850, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 8:
When dividing 1700 by 240, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 2666.77
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 2666.77 with a remainder of 0.02.
