511538 ÷ 3 
Let's see how many times 3 fits into 511538.

Moving on to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Moving on to step 2:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 0 after subtracting 21 from 21.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Let's proceed to step 3:
1 divided by 3 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 4:
3 can be fit into 15 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 1705.0
If we take 15 away from 15, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

Going ahead to step 5:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 17051.0
Subtract 3 from 3 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

On to step 6:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 170512.0
Subtracting 6 from 8 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.

Step 7:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 170512.6
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.

Let's proceed to step 8:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 170512.66
If we take 18 away from 20, we end up 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.

Our division results in 170512.66 with a remaining 0.002.
