We're dividing 66378261 by 242 
We want to divide 66378261 by 242.

Let's proceed to step 1:
242 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 242

Advancing to step 2:
66 divided by 242 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 242

Going ahead to step 3:
242 goes into 663 2 times with a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 484 from 663 and we're left with 179.
Fetch the next digit (7) from the dividend, attach it to 179 and continue: 1797 / 242

On to step 4:
When dividing 1797 by 242, we get 7 with a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 103 after subtracting 1694 from 1797.
Include the next digit (8) from the dividend after 103, then repeat: 1038 / 242

Let's proceed to step 5:
242 goes into 1038 4 times with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 274.0
If we take 968 away from 1038, we end up with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 242

Step 6:
242 can be fit into 702 2 times, resulting in a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 2742.0
Subtract 484 from 702 to get 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 242

Step 7:
242 can be fit into 2186 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 27429.0
Subtract 2178 from 2186 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 242

Advancing to step 8:
When dividing 81 by 242, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 274290.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
242 can be fit into 810 3 times, resulting in a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 274290.3
The remainder is 84 after subtracting 726 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
242 can be fit into 840 3 times, resulting in a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 274290.33
Deduct 726 from 840 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 274290.33, and the remainder is 0.114.
