We're dividing 631089 by 3 
We want to divide 631089 by 3.

Let's proceed to step 1:
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: 2.0
If we take 6 away from 6, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Let's proceed to step 2:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 3 away from 3, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Going ahead to step 3:
If we divide 1 by 3, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 210.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Advancing to step 4:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 2103.0
Subtract 9 from 10 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 5:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 21036.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Going ahead to step 6:
9 divided by 3 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 210363.0
Subtract 9 from 9 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.

On to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 210363.0
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.

Going ahead to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 210363.0
Deduct 0 from 0 and we're left 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.

Our division results in 210363.0 with a remaining 0.0.
