We look at the division of 877045 by 3 
Let's see how many times 3 fits into 877045.

Advancing to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Step 2:
The number 3 fits into 27 9 times, leaving 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 (7) from the dividend to 0 and continue with: 7 / 3

On to step 3:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
If we subtract 6 from 7, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Let's proceed to step 4:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 2923.0
Subtract 9 from 10 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Advancing to step 5:
3 goes into 14 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 29234.0
If we take 12 away from 14, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Step 6:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 292348.0
Deduct 24 from 25 and we're left 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.

Step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 292348.3
If we take 9 away from 10, 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.

Step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 292348.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 292348.33 and a remainder of 0.001.
