We're dividing 66389162 by 3 
We're looking to find how many times 3 goes into 66389162.

Moving on to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Advancing to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Let's proceed to step 3:
When dividing 3 by 3, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
Subtract 3 from 3 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Going ahead to step 4:
When dividing 8 by 3, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2212.0
The remainder is 2 after subtracting 6 from 8.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Step 5:
The number 3 fits into 29 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 22129.0
Subtract 27 from 29 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Step 6:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 221297.0
The remainder is 0 after subtracting 21 from 21.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Going ahead to step 7:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2212972.0
If we subtract 6 from 6, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Moving on to step 8:
2 divided by 3 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 22129720.0
Subtract 0 from 2 to 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 9:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 22129720.6
Subtracting 18 from 20 leaves us with 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:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 22129720.66
Subtract 18 from 20 to 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.

Our division results in 22129720.66 with a remaining 0.002.
