We look at the division of 240870 by 66 
We're looking to find how many times 66 goes into 240870.

Going ahead to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 66

On to step 2:
66 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 66

Going ahead to step 3:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 198 from 240 and we're left with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 66

Going ahead to step 4:
The number 66 fits into 428 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 396 from 428 leaves us with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 66

Let's proceed to step 5:
66 can be fit into 327 4 times, resulting in a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 364.0
Subtract 264 from 327 to get 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 66

On to step 6:
When dividing 630 by 66, we get 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 3649.0
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 66 fits into 360 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 3649.5
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 66, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3649.54
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
360 divided by 66 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3649.545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
66 goes into 300 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 3649.5454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
66 goes into 360 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3649.54545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
66 goes into 300 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3649.545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3649.5454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 3649.54545454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 3649.54545454 with a balance of 3.6e-08.
