Let's divide 563938 by 3
We're looking to find how many times 3 goes into 563938.

Going ahead to step 1:
3 goes into 5 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Step 2:
3 goes into 26 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 24 from 26 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Going ahead to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
The remainder is 2 after subtracting 21 from 23.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

On to step 4:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1879.0
Subtract 27 from 29 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Going ahead to step 5:
3 goes into 23 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 18797.0
If we take 21 away from 23, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Moving on to step 6:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 187979.0
Deduct 27 from 28 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.

Advancing to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 187979.3
Subtracting 9 from 10 leaves us 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.

Let's proceed to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 187979.33
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.

The final outcome is 187979.33, with a leftover of 0.001.
