66331209 ÷ 4 
We're looking to find how many times 4 goes into 66331209.

Let's proceed to step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Let's proceed to step 2:
26 divided by 4 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 24 from 26 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Let's proceed to step 3:
4 goes into 23 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 165.0
Subtract 20 from 23 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Step 4:
33 divided by 4 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1658.0
Deduct 32 from 33 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 4

Moving on to step 5:
If we divide 11 by 4, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 16582.0
Deduct 8 from 11 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 4

Moving on to step 6:
4 can be fit into 32 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 165828.0
Deduct 32 from 32 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Let's proceed to step 7:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1658280.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Going ahead to step 8:
4 goes into 9 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 16582802.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
4 goes into 10 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 16582802.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 16582802.25
If we take 20 away from 20, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16582802.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16582802.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 16582802.25, and the remainder is 0.0.
