We're dividing 261903 by 3 
Let's see how many times 3 fits into 261903.

Let's proceed to step 1:
2 divided by 3 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

Moving on to step 2:
When dividing 26 by 3, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 24 from 26 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Advancing to step 3:
21 divided by 3 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 87.0
If we take 21 away from 21, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Let's proceed to step 4:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 873.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 5:
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: 8730.0
Subtract 0 from 0 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Advancing to step 6:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 87301.0
If we subtract 3 from 3, 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 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 87301.0
Subtracting 0 from 0 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.

Going ahead to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 87301.0
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 87301.0 with a remaining 0.0.
