Let's divide 635515 by 3
Let's see how many times 3 fits into 635515.

On to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

On to step 2:
If we divide 3 by 3, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

On to step 3:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 211.0
If we take 3 away from 5, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Advancing to step 4:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 2118.0
If we subtract 24 from 25, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Going ahead to step 5:
When dividing 11 by 3, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 21183.0
Deduct 9 from 11 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

On to step 6:
25 divided by 3 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 211838.0
Subtracting 24 from 25 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.

Step 7:
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: 211838.3
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.

Moving on to step 8:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 211838.33
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.

The final result is 211838.33 with a remainder of 0.001.
