870530 divided by 3 
We want to divide 870530 by 3.

On to step 1:
8 divided by 3 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 3

On to step 2:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 27 away from 27, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

On to step 3:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Going ahead to step 4:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2901.0
The remainder is 2 after subtracting 3 from 5.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Step 5:
When dividing 23 by 3, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 29017.0
Subtracting 21 from 23 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

On to step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 290176.0
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.

Going ahead to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 290176.6
If we subtract 18 from 20, 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.

Let's proceed to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 290176.66
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.

The final result is 290176.66 with a remainder of 0.002.
