618393 ÷ 3 
We want to figure out the number of times 618393 can be divided by 3.

Let's proceed to step 1:
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: 2.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Going ahead to step 2:
When dividing 1 by 3, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Moving on to step 3:
The number 3 fits into 18 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 206.0
If we subtract 18 from 18, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

On to step 4:
3 divided by 3 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 2061.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Step 5:
3 goes into 9 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 20613.0
Subtract 9 from 9 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Step 6:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 206131.0
The remainder is 0 after subtracting 3 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 206131.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 206131.0
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.

After the division, we end up with 206131.0 and a remainder of 0.0.
