We divide 81966241 by 16
We want to figure out the number of times 81966241 can be divided by 16.

Moving on to step 1:
If we divide 8 by 16, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 16

Advancing to step 2:
16 goes into 81 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 80 away from 81, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 16

On to step 3:
The number 16 fits into 19 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 16 from 19, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 16

On to step 4:
The number 16 fits into 36 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 512.0
Subtract 32 from 36 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 16

Going ahead to step 5:
16 goes into 46 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 5122.0
Subtract 32 from 46 to get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 16

Going ahead to step 6:
142 divided by 16 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 51228.0
The remainder is 14 after subtracting 128 from 142.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 16

Step 7:
144 divided by 16 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 512289.0
The remainder is 0 after subtracting 144 from 144.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 16

Moving on to step 8:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 5122890.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
10 divided by 16 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5122890.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
16 can be fit into 100 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 5122890.06
Deduct 96 from 100 and we're left with 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 11:
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: 5122890.062
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.

Moving on to step 12:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5122890.0625
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.

Let's proceed to step 13:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5122890.0625
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 14:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5122890.0625
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 5122890.0625 with a balance of 0.0.
