55210454 ÷ 824 
The aim is to understand the frequency of 824 in 55210454.

Step 1:
824 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 824

Step 2:
The number 824 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 824

Let's proceed to step 3:
When dividing 552 by 824, we get 0 with a remainder of 552.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 552 after subtracting 0 from 552.
Include the next digit (1) from the dividend after 552, then repeat: 5521 / 824

Let's proceed to step 4:
When dividing 5521 by 824, we get 6 with a remainder of 577.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 4944 from 5521 leaves us with 577.
Bring next digit (0) of the dividend behind the 577 and repeat the process: 5770 / 824

Going ahead to step 5:
824 can be fit into 5770 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 5768 from 5770 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 824

Step 6:
If we divide 24 by 824, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 670.0
If we subtract 0 from 24, we get 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 824

Step 7:
824 goes into 245 0 times with a remainder of 245.
Use 0 as the next digit of our solution. 
Result so far: 6700.0
If we subtract 0 from 245, we get 245.
Append the next digit (4) from the dividend to 245 and continue with: 2454 / 824

Step 8:
2454 divided by 824 is 2 with a remainder of 806.
Put 2 as the next digit of the answer. 
Result so far: 67002.0
Subtracting 1648 from 2454 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Going ahead to step 9:
824 can be fit into 8060 9 times, resulting in a remainder of 644.
Record the quotient 9 as the next digit in the result. 
Result so far: 67002.9
Deduct 7416 from 8060 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 10:
If we divide 6440 by 824, we get 7 and a remainder of 672.
The number 7 becomes the next digit in our result. 
Result so far: 67002.97
Deduct 5768 from 6440 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.

Going ahead to step 11:
When dividing 6720 by 824, we get 8 with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 67002.978
The remainder is 128 after subtracting 6592 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
824 can be fit into 1280 1 times, resulting in a remainder of 456.
Use 1 as the next digit of our solution. 
Result so far: 67002.9781
Subtracting 824 from 1280 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 13:
824 goes into 4560 5 times with a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 67002.97815
The remainder is 440 after subtracting 4120 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 14:
824 can be fit into 4400 5 times, resulting in a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 67002.978155
Subtract 4120 from 4400 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 67002.978155 with a remainder of 2.8e-05.
