We're dividing 812791 by 16 
Our goal is to divide 812791 by 16.

Going ahead to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 16

Let's proceed to step 2:
16 can be fit into 81 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 16

Let's proceed to step 3:
If we divide 12 by 16, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 12, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 16

On to step 4:
16 goes into 127 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 507.0
Deduct 112 from 127 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 16

Going ahead to step 5:
16 can be fit into 159 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 5079.0
Subtracting 144 from 159 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 16

On to step 6:
151 divided by 16 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 50799.0
The remainder is 7 after subtracting 144 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
70 divided by 16 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 50799.4
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 16, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 50799.43
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.

Advancing to step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 50799.437
If we subtract 112 from 120, we get 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 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 50799.4375
Deduct 80 from 80 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.

Advancing to step 11:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50799.4375
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.

Advancing to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50799.4375
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 result is 50799.4375 with a remainder of 0.0.
