We're dividing 943949 by 3 
We want to figure out the number of times 943949 can be divided by 3.

Going ahead to step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Moving on to step 2:
When dividing 4 by 3, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 1 after subtracting 3 from 4.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Advancing to step 3:
If we divide 13 by 3, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 314.0
Subtract 12 from 13 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Step 4:
19 divided by 3 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3146.0
If we subtract 18 from 19, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Moving on to step 5:
If we divide 14 by 3, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 31464.0
The remainder is 2 after subtracting 12 from 14.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Advancing to step 6:
3 goes into 29 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 314649.0
If we subtract 27 from 29, we 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:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 314649.6
Deduct 18 from 20 and we're left 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.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 314649.66
Deduct 18 from 20 and we're left 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 314649.66 with a remaining 0.002.
