We're dividing 276491 by 3 
We want to figure out the number of times 276491 can be divided by 3.

Step 1:
If we divide 2 by 3, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

On to step 2:
27 divided by 3 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 27 from 27 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

On to step 3:
6 divided by 3 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Moving on to step 4:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 921.0
Deduct 3 from 4 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Step 5:
The number 3 fits into 19 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 9216.0
If we take 18 away from 19, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

On to step 6:
11 divided by 3 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 92163.0
If we subtract 9 from 11, 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.

On to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 92163.6
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:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 92163.66
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.

The quotient of the division is 92163.66, and the remainder is 0.002.
