821846 ÷ 16 
We're looking to find how many times 16 goes into 821846.

Moving on to step 1:
8 divided by 16 is 0 with 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.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 16

Step 2:
82 divided by 16 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 80 away from 82, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 16

Step 3:
The number 16 fits into 21 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 16 away from 21, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 16

Moving on to step 4:
58 divided by 16 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
Subtract 48 from 58 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 16

Step 5:
The number 16 fits into 104 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 5136.0
If we take 96 away from 104, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 16

Step 6:
If we divide 86 by 16, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 51365.0
If we subtract 80 from 86, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 51365.3
Subtracting 48 from 60 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 51365.37
Subtract 112 from 120 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.

Moving on to step 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 51365.375
If we subtract 80 from 80, we 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.

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: 51365.375
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.

On to step 11:
0 divided by 16 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51365.375
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 outcome is 51365.375, with a leftover of 0.0.
