286649 divided by 66 
We want to divide 286649 by 66.

On to step 1:
2 divided by 66 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 66

Advancing 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.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 66

On to step 3:
286 divided by 66 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 264 from 286 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 66

Moving on to step 4:
66 goes into 226 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 28 after subtracting 198 from 226.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 66

Moving on to step 5:
66 can be fit into 284 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 434.0
Subtracting 264 from 284 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 66

Step 6:
66 goes into 209 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 4343.0
Subtracting 198 from 209 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 66 fits into 110 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 4343.1
Subtracting 66 from 110 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
440 divided by 66 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 4343.16
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
The number 66 fits into 440 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 4343.166
If we subtract 396 from 440, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 4343.166, with a leftover of 0.0044.
