Let's divide 543909 by 16
We want to figure out the number of times 543909 can be divided by 16.

Step 1:
5 divided by 16 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 16

Moving on to step 2:
16 goes into 54 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 48 away from 54, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 16

Moving on to step 3:
16 goes into 63 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 48 from 63 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 16

Step 4:
When dividing 159 by 16, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 339.0
Subtract 144 from 159 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 16

On to step 5:
150 divided by 16 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 3399.0
The remainder is 6 after subtracting 144 from 150.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 16

On to step 6:
The number 16 fits into 69 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 33994.0
Subtract 64 from 69 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
16 can be fit into 50 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 33994.3
If we take 48 away from 50, we end up 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.

Let's proceed to step 8:
The number 16 fits into 20 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 33994.31
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 33994.312
Subtracting 32 from 40 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33994.3125
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33994.3125
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.

On to step 12:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33994.3125
Deduct 0 from 0 and we're left 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.

After the division, we end up with 33994.3125 and a remainder of 0.0.
