Let's divide 236346 by 509
We want to divide 236346 by 509.

On to step 1:
2 divided by 509 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 509

On to step 2:
509 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 509

On to step 3:
236 divided by 509 is 0 with a remainder of 236.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 236 after subtracting 0 from 236.
Include the next digit (3) from the dividend after 236, then repeat: 2363 / 509

Step 4:
The number 509 fits into 2363 4 times, leaving a remainder of 327.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2036 from 2363 leaves us with 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 509

Moving on to step 5:
When dividing 3274 by 509, we get 6 with a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 220 after subtracting 3054 from 3274.
Bring next digit (6) of the dividend behind the 220 and repeat the process: 2206 / 509

Advancing to step 6:
If we divide 2206 by 509, we get 4 and a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
Subtract 2036 from 2206 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 7:
509 can be fit into 1700 3 times, resulting in a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 464.3
Subtracting 1527 from 1700 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 8:
509 goes into 1730 3 times with a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 464.33
Subtracting 1527 from 1730 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

After the division, we end up with 464.33 and a remainder of 0.203.
