64456 ÷ 3 
Let's see how many times 3 fits into 64456.

Step 1:
6 divided by 3 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Advancing to step 2:
When dividing 4 by 3, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 3 from 4, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Let's proceed to step 3:
3 can be fit into 14 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Advancing to step 4:
When dividing 25 by 3, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 2148.0
If we subtract 24 from 25, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

Moving on to step 5:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 21485.0
The remainder is 1 after subtracting 15 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 21485.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 21485.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 21485.33 and a remainder of 0.001.
