We're dividing 439503 by 16 
We're looking to find how many times 16 goes into 439503.

Let's proceed to step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 16

Going ahead to step 2:
The number 16 fits into 43 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 32 from 43 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 16

Step 3:
The number 16 fits into 119 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 112 away from 119, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 16

On to step 4:
75 divided by 16 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 274.0
If we take 64 away from 75, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 16

Going ahead to step 5:
The number 16 fits into 110 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 2746.0
Deduct 96 from 110 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 16

Advancing to step 6:
16 goes into 143 8 times with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 27468.0
The remainder is 15 after subtracting 128 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 16, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 27468.9
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 16, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 27468.93
If we take 48 away from 60, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 27468.937
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 27468.9375
Subtracting 80 from 80 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.

On to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 27468.9375
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.

On to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27468.9375
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.

The final outcome is 27468.9375, with a leftover of 0.0.
