5547431 ÷ 820 
The aim is to understand the frequency of 820 in 5547431.

Let's proceed to step 1:
5 divided by 820 is 0 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.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 820

Step 2:
820 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 820

On to step 3:
When dividing 554 by 820, we get 0 with a remainder of 554.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 554, we get 554.
Bring next digit (7) of the dividend behind the 554 and repeat the process: 5547 / 820

Moving on to step 4:
When dividing 5547 by 820, we get 6 with a remainder of 627.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 4920 from 5547, we get 627.
Append the next digit (4) from the dividend to 627 and continue with: 6274 / 820

On to step 5:
If we divide 6274 by 820, we get 7 and a remainder of 534.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
The remainder is 534 after subtracting 5740 from 6274.
Include the next digit (3) from the dividend after 534, then repeat: 5343 / 820

Let's proceed to step 6:
820 can be fit into 5343 6 times, resulting in a remainder of 423.
The next digit of our result is 6. 
Result so far: 676.0
Subtract 4920 from 5343 to get 423.
Bring next digit (1) of the dividend behind the 423 and repeat the process: 4231 / 820

Advancing to step 7:
If we divide 4231 by 820, we get 5 and a remainder of 131.
The number 5 becomes the next digit in our result. 
Result so far: 6765.0
Subtracting 4100 from 4231 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 8:
820 can be fit into 1310 1 times, resulting in a remainder of 490.
The next digit of our result is 1. 
Result so far: 6765.1
Deduct 820 from 1310 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 9:
If we divide 4900 by 820, we get 5 and a remainder of 800.
The next digit of our result is 5. 
Result so far: 6765.15
The remainder is 800 after subtracting 4100 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 10:
8000 divided by 820 is 9 with a remainder of 620.
Use 9 as the next digit of our solution. 
Result so far: 6765.159
Deduct 7380 from 8000 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 11:
820 goes into 6200 7 times with a remainder of 460.
Record the quotient 7 as the next digit in the result. 
Result so far: 6765.1597
Deduct 5740 from 6200 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
The number 820 fits into 4600 5 times, leaving a remainder of 500.
The next digit of our result is 5. 
Result so far: 6765.15975
If we subtract 4100 from 4600, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 13:
If we divide 5000 by 820, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 6765.159756
Subtracting 4920 from 5000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
820 can be fit into 800 0 times, resulting in a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 6765.159756
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 15:
If we divide 8000 by 820, we get 9 and a remainder of 620.
The next digit of our result is 9. 
Result so far: 6765.15975609
Subtract 7380 from 8000 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

After the division, we end up with 6765.15975609 and a remainder of 6.2e-07.
