339742 divided by 16 
We want to figure out the number of times 339742 can be divided by 16.

Going ahead to step 1:
3 divided by 16 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 16

Step 2:
33 divided by 16 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 32 away from 33, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 16

Moving on to step 3:
16 goes into 19 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 16 from 19 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 16

On to step 4:
If we divide 37 by 16, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
The remainder is 5 after subtracting 32 from 37.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 16

Moving on to step 5:
When dividing 54 by 16, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 2123.0
Subtracting 48 from 54 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 16

Advancing to step 6:
The number 16 fits into 62 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 21233.0
If we take 48 away from 62, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
If we divide 140 by 16, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 21233.8
Deduct 128 from 140 and we're left 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.

Let's proceed to step 8:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 21233.87
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
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: 21233.875
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.

Advancing to step 10:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21233.875
Subtract 0 from 0 to 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.

Advancing to step 11:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21233.875
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.

In conclusion, the division gives 21233.875 with a balance of 0.0.
