Let's divide 77450505 by 809
The aim is to understand the frequency of 809 in 77450505.

Let's proceed to step 1:
809 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 809

Advancing to step 2:
809 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 809

Moving on to step 3:
774 divided by 809 is 0 with a remainder of 774.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 774 to get 774.
Fetch the next digit (5) from the dividend, attach it to 774 and continue: 7745 / 809

Advancing to step 4:
When dividing 7745 by 809, we get 9 with a remainder of 464.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7281 from 7745 leaves us with 464.
Include the next digit (0) from the dividend after 464, then repeat: 4640 / 809

Step 5:
If we divide 4640 by 809, we get 5 and a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtracting 4045 from 4640 leaves us with 595.
Bring next digit (5) of the dividend behind the 595 and repeat the process: 5955 / 809

Advancing to step 6:
809 can be fit into 5955 7 times, resulting in a remainder of 292.
Use 7 as the next digit of our solution. 
Result so far: 957.0
The remainder is 292 after subtracting 5663 from 5955.
Bring next digit (0) of the dividend behind the 292 and repeat the process: 2920 / 809

Going ahead to step 7:
809 goes into 2920 3 times with a remainder of 493.
The number 3 becomes the next digit in our result. 
Result so far: 9573.0
If we subtract 2427 from 2920, we get 493.
Bring next digit (5) of the dividend behind the 493 and repeat the process: 4935 / 809

Moving on to step 8:
4935 divided by 809 is 6 with a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 95736.0
Subtract 4854 from 4935 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
810 divided by 809 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 95736.1
The remainder is 1 after subtracting 809 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
The number 809 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 95736.1
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 809 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 95736.1
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 95736.1 with a balance of 0.01.
