803985 ÷ 16 
Let's see how many times 16 fits into 803985.

Let's proceed to step 1:
The number 16 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 16

Let's proceed to step 2:
16 goes into 80 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 80 from 80 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 16

On to step 3:
The number 16 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 16

Moving on to step 4:
When dividing 39 by 16, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 502.0
If we subtract 32 from 39, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 16

Step 5:
78 divided by 16 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 5024.0
Deduct 64 from 78 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 16

On to step 6:
145 divided by 16 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 50249.0
Deduct 144 from 145 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.

On to step 7:
16 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 50249.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 16, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 50249.06
If we take 96 away from 100, we end up 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.

Going ahead 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: 50249.062
Deduct 32 from 40 and we're left 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 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 50249.0625
Subtracting 80 from 80 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.

Let's proceed to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 50249.0625
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.

Let's proceed to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50249.0625
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.

After the division, we end up with 50249.0625 and a remainder of 0.0.
