40496616 ÷ 816 
The aim is to understand the frequency of 816 in 40496616.

Advancing to step 1:
If we divide 4 by 816, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 816

Let's proceed to step 2:
The number 816 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 816

Let's proceed to step 3:
816 can be fit into 404 0 times, resulting in a remainder of 404.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 404 and we're left with 404.
Bring next digit (9) of the dividend behind the 404 and repeat the process: 4049 / 816

On to step 4:
The number 816 fits into 4049 4 times, leaving a remainder of 785.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3264 from 4049 and we're left with 785.
Bring next digit (6) of the dividend behind the 785 and repeat the process: 7856 / 816

Let's proceed to step 5:
816 goes into 7856 9 times with a remainder of 512.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 7344 from 7856 leaves us with 512.
Include the next digit (6) from the dividend after 512, then repeat: 5126 / 816

Going ahead to step 6:
The number 816 fits into 5126 6 times, leaving a remainder of 230.
Put 6 as the next digit of the answer. 
Result so far: 496.0
Deduct 4896 from 5126 and we're left with 230.
Include the next digit (1) from the dividend after 230, then repeat: 2301 / 816

Let's proceed to step 7:
When dividing 2301 by 816, we get 2 with a remainder of 669.
The number 2 becomes the next digit in our result. 
Result so far: 4962.0
If we subtract 1632 from 2301, we get 669.
Fetch the next digit (6) from the dividend, attach it to 669 and continue: 6696 / 816

Going ahead to step 8:
The number 816 fits into 6696 8 times, leaving a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 49628.0
If we subtract 6528 from 6696, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 9:
If we divide 1680 by 816, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 49628.2
If we subtract 1632 from 1680, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
The number 816 fits into 480 0 times, leaving a remainder of 480.
The next digit of our result is 0. 
Result so far: 49628.2
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
When dividing 4800 by 816, we get 5 with a remainder of 720.
Record the quotient 5 as the next digit in the result. 
Result so far: 49628.205
Subtracting 4080 from 4800 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 12:
816 can be fit into 7200 8 times, resulting in a remainder of 672.
Put 8 as the next digit of the answer. 
Result so far: 49628.2058
Deduct 6528 from 7200 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 13:
The number 816 fits into 6720 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 49628.20588
Deduct 6528 from 6720 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 49628.20588 with a remaining 0.000192.
