54939667 divided by 816 
The aim is to understand the frequency of 816 in 54939667.

Moving on to step 1:
When dividing 5 by 816, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 816

Step 2:
If we divide 54 by 816, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 816

Let's proceed to step 3:
816 can be fit into 549 0 times, resulting in a remainder of 549.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 549, we get 549.
Append the next digit (3) from the dividend to 549 and continue with: 5493 / 816

Let's proceed to step 4:
If we divide 5493 by 816, we get 6 and a remainder of 597.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4896 from 5493, we get 597.
Include the next digit (9) from the dividend after 597, then repeat: 5979 / 816

On to step 5:
816 can be fit into 5979 7 times, resulting in a remainder of 267.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 5712 from 5979 to get 267.
Include the next digit (6) from the dividend after 267, then repeat: 2676 / 816

Let's proceed to step 6:
816 can be fit into 2676 3 times, resulting in a remainder of 228.
The next digit of our result is 3. 
Result so far: 673.0
If we subtract 2448 from 2676, we get 228.
Fetch the next digit (6) from the dividend, attach it to 228 and continue: 2286 / 816

Let's proceed to step 7:
2286 divided by 816 is 2 with a remainder of 654.
Write down 2 as next digit of the result. 
Result so far: 6732.0
Deduct 1632 from 2286 and we're left with 654.
Bring next digit (7) of the dividend behind the 654 and repeat the process: 6547 / 816

Advancing to step 8:
816 goes into 6547 8 times with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 67328.0
Subtracting 6528 from 6547 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
816 can be fit into 190 0 times, resulting in a remainder of 190.
The next digit of our result is 0. 
Result so far: 67328.0
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
816 goes into 1900 2 times with a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 67328.02
Subtract 1632 from 1900 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 11:
816 can be fit into 2680 3 times, resulting in a remainder of 232.
Record the quotient 3 as the next digit in the result. 
Result so far: 67328.023
The remainder is 232 after subtracting 2448 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
2320 divided by 816 is 2 with a remainder of 688.
Use 2 as the next digit of our solution. 
Result so far: 67328.0232
If we take 1632 away from 2320, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 13:
If we divide 6880 by 816, we get 8 and a remainder of 352.
The next digit of our result is 8. 
Result so far: 67328.02328
Deduct 6528 from 6880 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
816 can be fit into 3520 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 67328.023284
If we subtract 3264 from 3520, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 15:
The number 816 fits into 2560 3 times, leaving a remainder of 112.
Use 3 as the next digit of our solution. 
Result so far: 67328.0232843
Deduct 2448 from 2560 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
The number 816 fits into 1120 1 times, leaving a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 67328.02328431
If we take 816 away from 1120, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

In conclusion, the division gives 67328.02328431 with a balance of 3.04e-07.
