Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 66

Moving on to step 2:
42 divided by 66 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 66

Moving on to step 3:
66 goes into 424 6 times with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 396 from 424 leaves us with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 66

Advancing to step 4:
If we divide 284 by 66, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 20 after subtracting 264 from 284.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 66

Moving on to step 5:
66 can be fit into 205 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 643.0
Subtract 198 from 205 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 66

Going ahead to step 6:
The number 66 fits into 78 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 6431.0
Deduct 66 from 78 and we're left 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.

Step 7:
If we divide 120 by 66, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6431.1
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 6431.18
Deduct 528 from 540 and we're left 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.

Step 9:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6431.181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
540 divided by 66 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 6431.1818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 66 is 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 6431.18181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
If we divide 540 by 66, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 6431.181818
Deduct 528 from 540 and we're left 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.

Moving on to step 13:
120 divided by 66 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 6431.1818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
When dividing 540 by 66, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 6431.18181818
If we subtract 528 from 540, 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.

The final outcome is 6431.18181818, with a leftover of 1.2e-08.
