Let's divide 209135 by 4
We're looking to find how many times 4 goes into 209135.

Step 1:
4 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Going ahead to step 2:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 20 from 20, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Step 3:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 8 from 9, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

On to step 4:
When dividing 11 by 4, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 522.0
If we subtract 8 from 11, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

On to step 5:
If we divide 33 by 4, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 5228.0
Deduct 32 from 33 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 4

Let's proceed to step 6:
4 goes into 15 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 52283.0
If we subtract 12 from 15, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 52283.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 52283.75
Subtracting 20 from 20 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 52283.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 52283.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 52283.75 with a remainder of 0.0.
