We divide 280645 by 66
We want to divide 280645 by 66.

Moving on 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
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 66

On to step 2:
The number 66 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 66

Let's proceed to step 3:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 264 away from 280, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 66

Step 4:
The number 66 fits into 166 2 times, leaving a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 132 from 166 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 66

Advancing to step 5:
66 can be fit into 344 5 times, resulting in a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 425.0
Deduct 330 from 344 and we're left with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 66

Let's proceed to step 6:
The number 66 fits into 145 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 4252.0
Subtract 132 from 145 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
If we divide 130 by 66, we get 1 and a remainder of 64.
The next digit of our result is 1. 
Result so far: 4252.1
Subtract 66 from 130 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.

Going ahead to step 8:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 4252.19
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.

Step 9:
460 divided by 66 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 4252.196
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.

Moving on to step 10:
If we divide 640 by 66, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 4252.1969
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.

Step 11:
If we divide 460 by 66, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4252.19696
If we take 396 away from 460, we end up 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.

Moving on to step 12:
66 goes into 640 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 4252.196969
If we subtract 594 from 640, we get 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 13:
66 goes into 460 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4252.1969696
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.

Moving on to step 14:
When dividing 640 by 66, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 4252.19696969
If we take 594 away from 640, we end up 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.

After the division, we end up with 4252.19696969 and a remainder of 4.6e-08.
