806173 ÷ 16 
We want to figure out the number of times 806173 can be divided 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
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 16

Moving on to step 2:
16 goes into 80 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 80 from 80 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 16

Going ahead to step 3:
When dividing 6 by 16, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 16

On to step 4:
If we divide 61 by 16, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 503.0
Subtract 48 from 61 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 16

Moving on to step 5:
16 goes into 137 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 5038.0
Subtract 128 from 137 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 16

Moving on to step 6:
If we divide 93 by 16, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 50385.0
Subtract 80 from 93 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
16 goes into 130 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 50385.8
Subtract 128 from 130 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 16, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 50385.81
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 16, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 50385.812
Subtract 32 from 40 to 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.

Let's proceed to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 50385.8125
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 11:
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: 50385.8125
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.

Advancing to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50385.8125
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 50385.8125 with a remainder of 0.0.
