We look at the division of 279123 by 42 
Our goal is to divide 279123 by 42.

Step 1:
42 goes into 2 0 times 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 / 42

Going ahead to step 2:
The number 42 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 42

On to step 3:
42 can be fit into 279 6 times, resulting in a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 252 from 279 and we're left with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 42

On to step 4:
42 can be fit into 271 6 times, resulting in a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 252 from 271 and we're left with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 42

On to step 5:
If we divide 192 by 42, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 664.0
If we subtract 168 from 192, we get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 42

Going ahead to step 6:
243 divided by 42 is 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 6645.0
If we take 210 away from 243, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
If we divide 330 by 42, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 6645.7
If we subtract 294 from 330, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 6645.78
If we take 336 away from 360, 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.

Going ahead to step 9:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 6645.785
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 6645.7857
Deduct 294 from 300 and we're left 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.

On to step 11:
If we divide 60 by 42, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 6645.78571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 6645.785714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 6645.7857142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 6645.78571428
The remainder is 24 after subtracting 336 from 360.
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 6645.78571428 with a balance of 2.4e-08.
