We look at the division of 339572 by 16 
We're looking to find how many times 16 goes into 339572.

On to step 1:
3 divided by 16 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 16

Moving on to step 2:
When dividing 33 by 16, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 32 from 33 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 16

Advancing to step 3:
When dividing 19 by 16, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 16 away from 19, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 16

On to step 4:
16 goes into 35 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtract 32 from 35 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 16

Let's proceed to step 5:
The number 16 fits into 37 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 2122.0
Deduct 32 from 37 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 16

On to step 6:
52 divided by 16 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 21223.0
The remainder is 4 after subtracting 48 from 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 16, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 21223.2
Subtract 32 from 40 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 8:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21223.25
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.

Let's proceed to step 9:
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: 21223.25
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.

Moving on to step 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21223.25
Subtracting 0 from 0 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.

The final result is 21223.25 with a remainder of 0.0.
