We look at the division of 279040 by 42 
Let's see how many times 42 fits into 279040.

Going ahead to step 1:
The number 42 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 42

Going ahead to step 2:
27 divided by 42 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 42

On to step 3:
279 divided by 42 is 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 252 from 279, we get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 42

Advancing to step 4:
42 goes into 270 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 66.0
If we take 252 away from 270, we end up with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 42

Moving on to step 5:
42 goes into 184 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 664.0
If we take 168 away from 184, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 42

Step 6:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 6643.0
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
340 divided by 42 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6643.8
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6643.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 6643.809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6643.8095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 6643.80952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 6643.809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 6643.8095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6643.8095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 6643.8095238 and a remainder of 4e-08.
