We look at the division of 821916 by 2 
We want to figure out the number of times 821916 can be divided by 2.

On to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Let's proceed to step 2:
2 goes into 2 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Let's proceed to step 3:
1 divided by 2 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 410.0
If we subtract 0 from 1, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Step 4:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4109.0
Subtract 18 from 19 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Advancing to step 5:
2 goes into 11 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 41095.0
Deduct 10 from 11 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Let's proceed to step 6:
16 divided by 2 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 410958.0
Subtract 16 from 16 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.

Going ahead to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 410958.0
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.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 410958.0
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.

The final result is 410958.0 with a remainder of 0.0.
