We look at the division of 79997269 by 505 
The aim is to understand the frequency of 505 in 79997269.

Let's proceed to step 1:
If we divide 7 by 505, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 505

Advancing to step 2:
505 goes into 79 0 times with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 505

Let's proceed to step 3:
The number 505 fits into 799 1 times, leaving a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 505 from 799 leaves us with 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 505

Let's proceed to step 4:
The number 505 fits into 2949 5 times, leaving a remainder of 424.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 424 after subtracting 2525 from 2949.
Grab the next digit (7) from the dividend, add it to 424, then carry on: 4247 / 505

Advancing to step 5:
The number 505 fits into 4247 8 times, leaving a remainder of 207.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we subtract 4040 from 4247, we get 207.
Bring next digit (2) of the dividend behind the 207 and repeat the process: 2072 / 505

Advancing to step 6:
When dividing 2072 by 505, we get 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 1584.0
Deduct 2020 from 2072 and we're left with 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 505

Moving on to step 7:
505 can be fit into 526 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 15841.0
If we subtract 505 from 526, we get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 505

Moving on to step 8:
219 divided by 505 is 0 with a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 158410.0
If we take 0 away from 219, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 9:
505 goes into 2190 4 times with a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 158410.4
Subtracting 2020 from 2190 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
If we divide 1700 by 505, we get 3 and a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 158410.43
If we take 1515 away from 1700, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 11:
When dividing 1850 by 505, we get 3 with a remainder of 335.
Put 3 as the next digit of the answer. 
Result so far: 158410.433
If we take 1515 away from 1850, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

After the division, we end up with 158410.433 and a remainder of 0.0335.
