Let's divide 279123 by 66
We want to figure out the number of times 279123 can be divided by 66.

Going ahead to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 66

Moving on 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
The remainder is 27 after subtracting 0 from 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 66

Advancing to step 3:
279 divided by 66 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 15 after subtracting 264 from 279.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 66

Moving on to step 4:
When dividing 151 by 66, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 132 from 151, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 66

Going ahead to step 5:
192 divided by 66 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 422.0
Deduct 132 from 192 and we're left with 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 66

Let's proceed to step 6:
If we divide 603 by 66, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 4229.0
Subtract 594 from 603 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
66 can be fit into 90 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 4229.1
Subtracting 66 from 90 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.

Step 8:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4229.13
If we subtract 198 from 240, we 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 9:
The number 66 fits into 420 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 4229.136
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4229.1363
Deduct 198 from 240 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.

Moving on to step 11:
66 goes into 420 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 4229.13636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
If we divide 240 by 66, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 4229.136363
If we subtract 198 from 240, we 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 13:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4229.1363636
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.

Advancing to step 14:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 4229.13636363
Deduct 198 from 240 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.

The final outcome is 4229.13636363, with a leftover of 4.2e-08.
