249684 ÷ 66 
We want to divide 249684 by 66.

Step 1:
66 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 66

Let's proceed to step 2:
The number 66 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 66

Let's proceed to step 3:
The number 66 fits into 249 3 times, leaving a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 198 from 249 to get 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 66

On to step 4:
When dividing 516 by 66, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 462 from 516 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 66

Let's proceed to step 5:
The number 66 fits into 548 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 378.0
If we take 528 away from 548, we end up with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 66

Going ahead to step 6:
The number 66 fits into 204 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 3783.0
If we take 198 away from 204, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 66, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 3783.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
The number 66 fits into 600 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 3783.09
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 66, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3783.09
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
600 divided by 66 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 3783.0909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
When dividing 60 by 66, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3783.0909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
66 can be fit into 600 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 3783.090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
When dividing 60 by 66, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3783.090909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 3783.09090909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 3783.09090909, with a leftover of 6e-09.
