Let's divide 521696 by 3
We're looking to find how many times 3 goes into 521696.

On to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Advancing to step 2:
3 goes into 22 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 21 from 22 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Moving on to step 3:
If we divide 11 by 3, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 173.0
If we subtract 9 from 11, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Let's proceed to step 4:
26 divided by 3 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1738.0
Subtract 24 from 26 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Let's proceed to step 5:
When dividing 29 by 3, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 17389.0
Subtract 27 from 29 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Step 6:
26 divided by 3 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 173898.0
The remainder is 2 after subtracting 24 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 173898.6
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.

On to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 173898.66
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.

The final outcome is 173898.66, with a leftover of 0.002.
