384400 divided by 3 
We want to figure out the number of times 384400 can be divided by 3.

Let's proceed to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Step 2:
If we divide 8 by 3, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 6 away from 8, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Moving on to step 3:
3 goes into 24 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 128.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Let's proceed 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: 1281.0
If we subtract 3 from 4, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Going ahead to step 5:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 12813.0
If we take 9 away from 10, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Let's proceed to step 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 128133.0
Deduct 9 from 10 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.

Advancing to step 7:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 128133.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 128133.33
Subtracting 9 from 10 leaves us 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.

Our division results in 128133.33 with a remaining 0.001.
