Let's divide 631449 by 3
Let's see how many times 3 fits into 631449.

Going ahead to step 1:
3 goes into 6 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Advancing to step 2:
If we divide 3 by 3, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Moving on to step 3:
1 divided by 3 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Going ahead to step 4:
When dividing 14 by 3, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2104.0
If we take 12 away from 14, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Advancing to step 5:
If we divide 24 by 3, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 21048.0
If we subtract 24 from 24, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Moving on to step 6:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 210483.0
Subtracting 9 from 9 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.

Step 7:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 210483.0
If we subtract 0 from 0, we 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.

Moving on to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 210483.0
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.

Our division results in 210483.0 with a remaining 0.0.
