280993 ÷ 66 
We're looking to find how many times 66 goes into 280993.

Let's proceed to step 1:
2 divided by 66 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 66

Let's proceed to step 2:
When dividing 28 by 66, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 66

Going ahead to step 3:
66 goes into 280 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 264 from 280 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 66

Going ahead to step 4:
If we divide 169 by 66, we get 2 and a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 132 from 169, we get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 66

Let's proceed to step 5:
If we divide 379 by 66, we get 5 and a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 425.0
The remainder is 49 after subtracting 330 from 379.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 66

Let's proceed to step 6:
66 can be fit into 493 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 4257.0
Subtract 462 from 493 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
66 goes into 310 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 4257.4
The remainder is 46 after subtracting 264 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 4257.46
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
66 goes into 640 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 4257.469
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 66, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 4257.4696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
640 divided by 66 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 4257.46969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4257.469696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
640 divided by 66 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 4257.4696969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4257.46969696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 4257.46969696 with a balance of 6.4e-08.
