We're dividing 936640 by 3 
Let's see how many times 3 fits into 936640.

Let's proceed to step 1:
9 divided by 3 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Moving on to step 2:
3 can be fit into 3 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Step 3:
3 goes into 6 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Step 4:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 3122.0
If we subtract 6 from 6, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Let's proceed to step 5:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31221.0
Deduct 3 from 4 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Moving on to step 6:
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: 312213.0
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.

Let's proceed to step 7:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 312213.3
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.

Step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 312213.33
Subtract 9 from 10 to 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.

In conclusion, the division gives 312213.33 with a balance of 0.001.
