15436 ÷ 4 
Let's see how many times 4 fits into 15436.

Step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

On to step 2:
4 can be fit into 15 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 12 from 15 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 4

Step 3:
If we divide 34 by 4, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 32 from 34 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Going ahead to step 4:
23 divided by 4 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 385.0
Subtract 20 from 23 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 4

Let's proceed to step 5:
4 can be fit into 36 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 3859.0
If we subtract 36 from 36, 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.

Step 6:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3859.0
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.

Step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3859.0
If we take 0 away from 0, we end up 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.

The final result is 3859.0 with a remainder of 0.0.
