We look at the division of 243872 by 42 
Our goal is to divide 243872 by 42.

On to step 1:
42 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 42

Advancing to step 2:
24 divided by 42 is 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 42

Moving on to step 3:
42 goes into 243 5 times with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 210 away from 243, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 42

Let's proceed to step 4:
42 goes into 338 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Deduct 336 from 338 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 42

Going ahead to step 5:
The number 42 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 580.0
Subtract 0 from 27 to get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 42

Step 6:
42 can be fit into 272 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 5806.0
Deduct 252 from 272 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 5806.4
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 5806.47
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
When dividing 260 by 42, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 5806.476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
42 goes into 80 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 5806.4761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
380 divided by 42 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 5806.47619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
20 divided by 42 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5806.47619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 5806.4761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 5806.47619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 5806.47619047 with a remaining 2.6e-08.
