623999 ÷ 3 
We want to figure out the number of times 623999 can be divided by 3.

Let's proceed to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Step 2:
2 divided by 3 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Going ahead to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 207.0
Subtract 21 from 23 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Advancing to step 4:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 2079.0
Subtracting 27 from 29 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Let's proceed to step 5:
29 divided by 3 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 20799.0
Subtract 27 from 29 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Let's proceed to step 6:
3 goes into 29 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 207999.0
The remainder is 2 after subtracting 27 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
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: 207999.6
If we take 18 away from 20, we end up 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.

Let's proceed to step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 207999.66
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.

The final result is 207999.66 with a remainder of 0.002.
