We're dividing 242142 by 90 
We're looking to find how many times 90 goes into 242142.

Moving on to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 90

On to step 2:
24 divided by 90 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 90

Let's proceed to step 3:
90 can be fit into 242 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 180 from 242 to get 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 90

Let's proceed to step 4:
The number 90 fits into 621 6 times, leaving a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 540 from 621 and we're left with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 90

Step 5:
814 divided by 90 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 269.0
Subtract 810 from 814 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 90

Let's proceed to step 6:
42 divided by 90 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 2690.0
If we subtract 0 from 42, 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.

Let's proceed to step 7:
90 can be fit into 420 4 times, resulting in a remainder of 60.
The next digit of our result is 4. 
Result so far: 2690.4
If we subtract 360 from 420, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
90 goes into 600 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 2690.46
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 2690.466
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 2690.466, and the remainder is 0.006.
