We look at the division of 661230 by 3 
We're looking to find how many times 3 goes into 661230.

Advancing to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Write down 2 as next digit of 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

Let's proceed to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

Let's proceed to step 3:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 220.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Let's proceed to step 4:
3 goes into 12 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 2204.0
If we take 12 away from 12, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

On to step 5:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 22041.0
If we take 3 away from 3, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Moving on to step 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 220410.0
If we take 0 away from 0, 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 7:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 220410.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 220410.0
If we take 0 away from 0, 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.

In conclusion, the division gives 220410.0 with a balance of 0.0.
