We look at the division of 416039 by 3 
Our goal is to divide 416039 by 3.

Moving on to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Going ahead to step 2:
3 goes into 11 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 9 from 11, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Moving on to step 3:
3 goes into 26 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Deduct 24 from 26 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Advancing to step 4:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1386.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

On to step 5:
23 divided by 3 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 13867.0
Subtracting 21 from 23 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

On to step 6:
29 divided by 3 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 138679.0
Subtracting 27 from 29 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.

Going ahead to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 138679.6
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.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 138679.66
If we subtract 18 from 20, 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.

The final result is 138679.66 with a remainder of 0.002.
