We look at the division of 24240 by 42 
We're looking to find how many times 42 goes into 24240.

Moving on to step 1:
42 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 42

On to step 2:
If we divide 24 by 42, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 42

On to step 3:
When dividing 242 by 42, we get 5 with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 210 from 242, we get 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 42

On to step 4:
When dividing 324 by 42, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 294 from 324, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 42

Going ahead to step 5:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 577.0
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
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: 577.1
If we take 42 away from 60, we end up 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.

Step 7:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 577.14
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 577.142
If we subtract 84 from 120, 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.

Step 9:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 577.1428
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 10:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 577.14285
Subtract 210 from 240 to 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 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 577.142857
If we take 294 away from 300, we end up 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 12:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 577.1428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 577.14285714
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.

The final outcome is 577.14285714, with a leftover of 1.2e-08.
