We look at the division of 66042356 by 522 
We want to divide 66042356 by 522.

On to step 1:
522 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 522

Moving on to step 2:
66 divided by 522 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 522

Going ahead to step 3:
522 goes into 660 1 times with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 522 from 660 leaves us with 138.
Bring next digit (4) of the dividend behind the 138 and repeat the process: 1384 / 522

Going ahead to step 4:
522 goes into 1384 2 times with a remainder of 340.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1044 from 1384 leaves us with 340.
Include the next digit (2) from the dividend after 340, then repeat: 3402 / 522

Advancing to step 5:
522 can be fit into 3402 6 times, resulting in a remainder of 270.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 3132 from 3402 to get 270.
Include the next digit (3) from the dividend after 270, then repeat: 2703 / 522

Step 6:
522 goes into 2703 5 times with a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 1265.0
If we take 2610 away from 2703, we end up with 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 522

Going ahead to step 7:
When dividing 935 by 522, we get 1 with a remainder of 413.
The number 1 becomes the next digit in our result. 
Result so far: 12651.0
If we take 522 away from 935, we end up with 413.
Bring next digit (6) of the dividend behind the 413 and repeat the process: 4136 / 522

Going ahead to step 8:
The number 522 fits into 4136 7 times, leaving a remainder of 482.
Write down 7 as next digit of the result. 
Result so far: 126517.0
The remainder is 482 after subtracting 3654 from 4136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 9:
4820 divided by 522 is 9 with a remainder of 122.
The number 9 becomes the next digit in our result. 
Result so far: 126517.9
Deduct 4698 from 4820 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
The number 522 fits into 1220 2 times, leaving a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 126517.92
The remainder is 176 after subtracting 1044 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 11:
When dividing 1760 by 522, we get 3 with a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 126517.923
The remainder is 194 after subtracting 1566 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 12:
If we divide 1940 by 522, we get 3 and a remainder of 374.
The next digit of our result is 3. 
Result so far: 126517.9233
If we subtract 1566 from 1940, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The final outcome is 126517.9233, with a leftover of 0.00374.
