We look at the division of 42812677 by 505 
The aim is to understand the frequency of 505 in 42812677.

Step 1:
The number 505 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 505

Advancing to step 2:
505 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 505

Moving on to step 3:
If we divide 428 by 505, we get 0 and a remainder of 428.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 428, we get 428.
Fetch the next digit (1) from the dividend, attach it to 428 and continue: 4281 / 505

Moving on to step 4:
505 goes into 4281 8 times with a remainder of 241.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 4040 from 4281 to get 241.
Include the next digit (2) from the dividend after 241, then repeat: 2412 / 505

Step 5:
505 can be fit into 2412 4 times, resulting in a remainder of 392.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 2020 from 2412 leaves us with 392.
Bring next digit (6) of the dividend behind the 392 and repeat the process: 3926 / 505

On to step 6:
If we divide 3926 by 505, we get 7 and a remainder of 391.
Use 7 as the next digit of our solution. 
Result so far: 847.0
The remainder is 391 after subtracting 3535 from 3926.
Grab the next digit (7) from the dividend, add it to 391, then carry on: 3917 / 505

Moving on to step 7:
3917 divided by 505 is 7 with a remainder of 382.
Record the quotient 7 as the next digit in the result. 
Result so far: 8477.0
Subtract 3535 from 3917 to get 382.
Bring next digit (7) of the dividend behind the 382 and repeat the process: 3827 / 505

Advancing to step 8:
505 can be fit into 3827 7 times, resulting in a remainder of 292.
The next digit of our result is 7. 
Result so far: 84777.0
Subtracting 3535 from 3827 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
505 can be fit into 2920 5 times, resulting in a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 84777.5
Subtracting 2525 from 2920 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 10:
When dividing 3950 by 505, we get 7 with a remainder of 415.
The next digit of our result is 7. 
Result so far: 84777.57
Subtract 3535 from 3950 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 11:
505 goes into 4150 8 times with a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 84777.578
Subtract 4040 from 4150 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
505 can be fit into 1100 2 times, resulting in a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 84777.5782
Subtracting 1010 from 1100 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
505 can be fit into 900 1 times, resulting in a remainder of 395.
Record the quotient 1 as the next digit in the result. 
Result so far: 84777.57821
If we take 505 away from 900, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 14:
505 can be fit into 3950 7 times, resulting in a remainder of 415.
Put 7 as the next digit of the answer. 
Result so far: 84777.578217
Subtracting 3535 from 3950 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 15:
When dividing 4150 by 505, we get 8 with a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 84777.5782178
Deduct 4040 from 4150 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 16:
1100 divided by 505 is 2 with a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 84777.57821782
Subtract 1010 from 1100 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 84777.57821782, with a leftover of 9e-08.
