We divide 879409 by 3
We're looking to find how many times 3 goes into 879409.

Advancing to step 1:
8 divided by 3 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

Advancing to step 2:
If we divide 27 by 3, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 27 from 27 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

On to step 3:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 293.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Step 4:
When dividing 4 by 3, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2931.0
Subtract 3 from 4 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Advancing to step 5:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 29313.0
The remainder is 1 after subtracting 9 from 10.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Moving on to step 6:
19 divided by 3 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 293136.0
If we take 18 away from 19, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 293136.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 293136.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 293136.33, and the remainder is 0.001.
