Let's divide 366423 by 3
Let's see how many times 3 fits into 366423.

Going ahead to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Let's proceed to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 6 from 6, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Moving on to step 3:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 122.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Moving on to step 4:
3 goes into 4 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1221.0
Subtract 3 from 4 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Let's proceed to step 5:
3 goes into 12 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12214.0
If we subtract 12 from 12, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Going ahead to step 6:
3 goes into 3 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 122141.0
Deduct 3 from 3 and we're left 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.

Going ahead to step 7:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 122141.0
Subtract 0 from 0 to get 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 8:
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: 122141.0
Deduct 0 from 0 and we're left 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 final result is 122141.0 with a remainder of 0.0.
