54725591 ÷ 806 
The aim is to understand the frequency of 806 in 54725591.

Let's proceed to step 1:
When dividing 5 by 806, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 806

Moving on to step 2:
54 divided by 806 is 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 806

Let's proceed to step 3:
The number 806 fits into 547 0 times, leaving a remainder of 547.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 547, we end up with 547.
Fetch the next digit (2) from the dividend, attach it to 547 and continue: 5472 / 806

Let's proceed to step 4:
When dividing 5472 by 806, we get 6 with a remainder of 636.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 4836 from 5472 leaves us with 636.
Bring next digit (5) of the dividend behind the 636 and repeat the process: 6365 / 806

Advancing to step 5:
6365 divided by 806 is 7 with a remainder of 723.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we subtract 5642 from 6365, we get 723.
Include the next digit (5) from the dividend after 723, then repeat: 7235 / 806

Let's proceed to step 6:
The number 806 fits into 7235 8 times, leaving a remainder of 787.
Put 8 as the next digit of the answer. 
Result so far: 678.0
Deduct 6448 from 7235 and we're left with 787.
Grab the next digit (9) from the dividend, add it to 787, then carry on: 7879 / 806

Step 7:
The number 806 fits into 7879 9 times, leaving a remainder of 625.
Put 9 as the next digit of the answer. 
Result so far: 6789.0
Deduct 7254 from 7879 and we're left with 625.
Grab the next digit (1) from the dividend, add it to 625, then carry on: 6251 / 806

Step 8:
806 goes into 6251 7 times with a remainder of 609.
Use 7 as the next digit of our solution. 
Result so far: 67897.0
Subtracting 5642 from 6251 leaves us with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

On to step 9:
806 goes into 6090 7 times with a remainder of 448.
The next digit of our result is 7. 
Result so far: 67897.7
If we subtract 5642 from 6090, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 10:
4480 divided by 806 is 5 with a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 67897.75
Subtracting 4030 from 4480 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 11:
806 can be fit into 4500 5 times, resulting in a remainder of 470.
The next digit of our result is 5. 
Result so far: 67897.755
Subtracting 4030 from 4500 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The quotient of the division is 67897.755, and the remainder is 0.047.
