538693 ÷ 3 
Let's see how many times 3 fits into 538693.

Step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

On to step 2:
If we divide 23 by 3, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 17.0
If we take 21 away from 23, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

On to step 3:
When dividing 28 by 3, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtracting 27 from 28 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Step 4:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1795.0
Deduct 15 from 16 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Let's proceed to step 5:
19 divided by 3 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 17956.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Advancing to step 6:
13 divided by 3 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 179564.0
The remainder is 1 after subtracting 12 from 13.
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:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 179564.3
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.

Going ahead to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 179564.33
If we subtract 9 from 10, we get 1.
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 179564.33 and a remainder of 0.001.
