We divide 869420 by 3
Let's see how many times 3 fits into 869420.

Advancing to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

On to step 2:
If we divide 26 by 3, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Let's proceed to step 3:
When dividing 29 by 3, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
If we subtract 27 from 29, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Step 4:
When dividing 24 by 3, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2898.0
Subtract 24 from 24 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Going ahead to step 5:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 28980.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 289806.0
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 289806.6
Subtract 18 from 20 to 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.

Step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 289806.66
Subtracting 18 from 20 leaves us 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 final result is 289806.66 with a remainder of 0.002.
