We look at the division of 673949 by 3 
Our goal is to divide 673949 by 3.

Moving on 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
Subtracting 6 from 6 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Going ahead to step 2:
When dividing 7 by 3, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 1 after subtracting 6 from 7.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Going ahead to step 3:
When dividing 13 by 3, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtracting 12 from 13 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

On to step 4:
The number 3 fits into 19 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 2246.0
Deduct 18 from 19 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

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: 22464.0
If we subtract 12 from 14, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Step 6:
The number 3 fits into 29 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 224649.0
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.

Advancing to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 224649.6
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.

Step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 224649.66
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.

The final result is 224649.66 with a remainder of 0.002.
