680042 divided by 16 
We're looking to find how many times 16 goes into 680042.

Going ahead to step 1:
6 divided by 16 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 16

Let's proceed to step 2:
16 can be fit into 68 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 64 from 68 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 16

Going ahead to step 3:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 32 from 40 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 16

Going ahead to step 4:
When dividing 80 by 16, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 425.0
Subtract 80 from 80 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 16

Going ahead to step 5:
If we divide 4 by 16, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 4250.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 16

Let's proceed to step 6:
42 divided by 16 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 42502.0
Subtracting 32 from 42 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 16, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 42502.6
If we subtract 96 from 100, we 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.

Let's proceed to step 8:
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: 42502.62
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 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 42502.625
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.

Let's proceed to step 10:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42502.625
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.

Let's proceed to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42502.625
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.

The final outcome is 42502.625, with a leftover of 0.0.
