We look at the division of 520877 by 3 
Our goal is to divide 520877 by 3.

Let's proceed to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Advancing to step 2:
If we divide 22 by 3, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 21 from 22 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Advancing to step 3:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
The remainder is 1 after subtracting 9 from 10.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Let's proceed to step 4:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 1736.0
Subtract 18 from 18 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

On to step 5:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 17362.0
Deduct 6 from 7 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Let's proceed to step 6:
3 can be fit into 17 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 173625.0
Subtracting 15 from 17 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.

Moving on to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 173625.6
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.

Step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 173625.66
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.

Our division results in 173625.66 with a remaining 0.002.
