819940 divided by 16 
We want to figure out the number of times 819940 can be divided by 16.

Moving on to step 1:
8 divided by 16 is 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 16

Going ahead to step 2:
16 can be fit into 81 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 80 from 81 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 16

Step 3:
When dividing 19 by 16, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 3 after subtracting 16 from 19.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 16

Advancing to step 4:
16 goes into 39 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
Deduct 32 from 39 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 16

On to step 5:
The number 16 fits into 74 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 5124.0
Deduct 64 from 74 and we're left with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 16

On to step 6:
If we divide 100 by 16, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 51246.0
Deduct 96 from 100 and we're left 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.

Let's proceed to step 7:
16 goes into 40 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 51246.2
If we subtract 32 from 40, 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.

Let's proceed to step 8:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 51246.25
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.

Step 9:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51246.25
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.

Advancing to step 10:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51246.25
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.

The final outcome is 51246.25, with a leftover of 0.0.
