430205 divided by 77 
The aim is to understand the frequency of 77 in 430205.

Going ahead to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 77

Step 2:
43 divided by 77 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 77

Moving on to step 3:
430 divided by 77 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 385 away from 430, we end up with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 77

Going ahead to step 4:
77 can be fit into 452 5 times, resulting in a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 385 from 452 to get 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 77

Step 5:
The number 77 fits into 670 8 times, leaving a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 558.0
If we take 616 away from 670, we end up with 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 77

Let's proceed to step 6:
The number 77 fits into 545 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 5587.0
Subtract 539 from 545 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 77 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 5587.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
The number 77 fits into 600 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 5587.07
If we subtract 539 from 600, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 5587.077
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 5587.077 and a remainder of 0.0071.
