278973 ÷ 66 
We want to divide 278973 by 66.

Moving on to step 1:
When dividing 2 by 66, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 66

Let's proceed to step 2:
The number 66 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 66

Moving on to step 3:
66 goes into 278 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 14 after subtracting 264 from 278.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 66

Moving on to step 4:
If we divide 149 by 66, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 132 from 149 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 66

Going ahead to step 5:
66 goes into 177 2 times with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 422.0
Subtracting 132 from 177 leaves us with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 66

On to step 6:
453 divided by 66 is 6 with a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 4226.0
Subtract 396 from 453 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
66 can be fit into 570 8 times, resulting in a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 4226.8
Deduct 528 from 570 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
66 goes into 420 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 4226.86
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4226.863
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 66, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 4226.8636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 66, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 4226.86363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
When dividing 420 by 66, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4226.863636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 66, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 4226.8636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
420 divided by 66 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 4226.86363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 4226.86363636 with a balance of 2.4e-08.
