803453 ÷ 16 
We want to figure out the number of times 803453 can be divided by 16.

Moving on to step 1:
If we divide 8 by 16, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 16

Step 2:
If we divide 80 by 16, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 80 from 80.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 16

Moving on to step 3:
16 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 16

Advancing to step 4:
16 can be fit into 34 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 502.0
If we subtract 32 from 34, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 16

Step 5:
When dividing 25 by 16, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 5021.0
Deduct 16 from 25 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 16

Advancing to step 6:
16 can be fit into 93 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 50215.0
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.

Let's proceed to step 7:
If we divide 130 by 16, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 50215.8
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.

Let's proceed to step 8:
When dividing 20 by 16, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 50215.81
If we take 16 away from 20, 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:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 50215.812
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.

Step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 50215.8125
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.

Moving on to step 11:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50215.8125
Deduct 0 from 0 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 12:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50215.8125
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.

Our division results in 50215.8125 with a remaining 0.0.
