We're dividing 71324725 by 505 
The aim is to understand the frequency of 505 in 71324725.

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
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 505

Step 2:
When dividing 71 by 505, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 505

Let's proceed to step 3:
505 goes into 713 1 times with a remainder of 208.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 505 from 713 to get 208.
Append the next digit (2) from the dividend to 208 and continue with: 2082 / 505

Moving on to step 4:
When dividing 2082 by 505, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2020 away from 2082, we end up with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 505

Let's proceed to step 5:
The number 505 fits into 624 1 times, leaving a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 119 after subtracting 505 from 624.
Take the next digit (7) from the dividend and append it to 119, then repeat: 1197 / 505

Step 6:
If we divide 1197 by 505, we get 2 and a remainder of 187.
Put 2 as the next digit of the answer. 
Result so far: 1412.0
If we subtract 1010 from 1197, we get 187.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 505

Moving on to step 7:
When dividing 1872 by 505, we get 3 with a remainder of 357.
Put 3 as the next digit of the answer. 
Result so far: 14123.0
The remainder is 357 after subtracting 1515 from 1872.
Bring next digit (5) of the dividend behind the 357 and repeat the process: 3575 / 505

Let's proceed to step 8:
The number 505 fits into 3575 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 141237.0
If we take 3535 away from 3575, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 505 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 141237.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
4000 divided by 505 is 7 with a remainder of 465.
Use 7 as the next digit of our solution. 
Result so far: 141237.07
If we take 3535 away from 4000, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 11:
When dividing 4650 by 505, we get 9 with a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 141237.079
Subtracting 4545 from 4650 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
When dividing 1050 by 505, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 141237.0792
Deduct 1010 from 1050 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
505 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 141237.0792
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 14:
505 goes into 4000 7 times with a remainder of 465.
Write down 7 as next digit of the result. 
Result so far: 141237.079207
If we subtract 3535 from 4000, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 15:
The number 505 fits into 4650 9 times, leaving a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 141237.0792079
If we take 4545 away from 4650, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 16:
If we divide 1050 by 505, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 141237.07920792
Deduct 1010 from 1050 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 141237.07920792 with a remainder of 4e-08.
