We're dividing 673239 by 16 
Let's see how many times 16 fits into 673239.

Let's proceed to step 1:
If we divide 6 by 16, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 16

Going ahead to step 2:
When dividing 67 by 16, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 64 from 67 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 16

On to step 3:
16 can be fit into 33 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 32 from 33, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 16

Advancing to step 4:
12 divided by 16 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 420.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 16

Step 5:
16 can be fit into 123 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 4207.0
If we subtract 112 from 123, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 16

Going ahead to step 6:
When dividing 119 by 16, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 42077.0
Subtracting 112 from 119 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 16 fits into 70 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 42077.4
Subtracting 64 from 70 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
16 goes into 60 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 42077.43
Subtracting 48 from 60 leaves us 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:
120 divided by 16 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 42077.437
If we take 112 away from 120, we end up 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:
80 divided by 16 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 42077.4375
Subtract 80 from 80 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.

Moving on to step 11:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42077.4375
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.

Let's proceed to step 12:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42077.4375
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.

In conclusion, the division gives 42077.4375 with a balance of 0.0.
