81674566 divided by 16 
We want to divide 81674566 by 16.

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
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 16

On to step 2:
16 can be fit into 81 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 80 from 81 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 16

Moving on to step 3:
16 divided by 16 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we take 16 away from 16, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 16

On to step 4:
When dividing 7 by 16, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 510.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 16

Moving on to step 5:
The number 16 fits into 74 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 5104.0
If we take 64 away from 74, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 16

Going ahead to step 6:
16 goes into 105 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 51046.0
Subtracting 96 from 105 leaves us with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 16

Going ahead to step 7:
When dividing 96 by 16, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 510466.0
If we subtract 96 from 96, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 16

Step 8:
16 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 5104660.0
Subtracting 0 from 6 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.

Going ahead to step 9:
When dividing 60 by 16, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 5104660.3
If we subtract 48 from 60, we get 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 10:
The number 16 fits into 120 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 5104660.37
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.

Moving on to step 11:
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: 5104660.375
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.

On to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5104660.375
The remainder is 0 after subtracting 0 from 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 13:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5104660.375
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.

The final result is 5104660.375 with a remainder of 0.0.
