999545 ÷ 3 
We want to figure out the number of times 999545 can be divided by 3.

Advancing to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Going ahead to step 2:
When dividing 9 by 3, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Going ahead to step 3:
If we divide 9 by 3, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 333.0
If we take 9 away from 9, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Going ahead to step 4:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 3331.0
If we subtract 3 from 5, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Step 5:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 33318.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Let's proceed to step 6:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 333181.0
Subtract 3 from 5 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 333181.6
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.

On to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 333181.66
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.

Our division results in 333181.66 with a remaining 0.002.
