We divide 666930 by 16
We want to figure out the number of times 666930 can be divided by 16.

On to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 16

Step 2:
The number 16 fits into 66 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 64 away from 66, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 16

Going ahead to step 3:
16 goes into 26 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 16 from 26 leaves us with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 16

Going ahead to step 4:
If we divide 109 by 16, we get 6 and a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 416.0
If we subtract 96 from 109, we get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 16

Going ahead to step 5:
When dividing 133 by 16, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 4168.0
Deduct 128 from 133 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 16

Let's proceed to step 6:
If we divide 50 by 16, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 41683.0
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
16 goes into 20 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 41683.1
Subtract 16 from 20 to 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.

Going ahead to step 8:
If we divide 40 by 16, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 41683.12
The remainder is 8 after subtracting 32 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 41683.125
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
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: 41683.125
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.

Step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41683.125
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.

The final result is 41683.125 with a remainder of 0.0.
