91586469 ÷ 505 
The aim is to understand the frequency of 505 in 91586469.

Going ahead to step 1:
If we divide 9 by 505, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 505

Let's proceed to step 2:
The number 505 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 505

Moving on to step 3:
505 goes into 915 1 times with a remainder of 410.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 410 after subtracting 505 from 915.
Append the next digit (8) from the dividend to 410 and continue with: 4108 / 505

Going ahead to step 4:
The number 505 fits into 4108 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 4040 from 4108 and we're left with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 505

Advancing to step 5:
686 divided by 505 is 1 with a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Deduct 505 from 686 and we're left with 181.
Include the next digit (4) from the dividend after 181, then repeat: 1814 / 505

On to step 6:
505 can be fit into 1814 3 times, resulting in a remainder of 299.
Write down 3 as next digit of the result. 
Result so far: 1813.0
The remainder is 299 after subtracting 1515 from 1814.
Grab the next digit (6) from the dividend, add it to 299, then carry on: 2996 / 505

Moving on to step 7:
505 can be fit into 2996 5 times, resulting in a remainder of 471.
Write down 5 as next digit of the result. 
Result so far: 18135.0
If we take 2525 away from 2996, we end up with 471.
Take the next digit (9) from the dividend and append it to 471, then repeat: 4719 / 505

Step 8:
505 goes into 4719 9 times with a remainder of 174.
The number 9 becomes the next digit in our result. 
Result so far: 181359.0
Subtracting 4545 from 4719 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
1740 divided by 505 is 3 with a remainder of 225.
Write down 3 as next digit of the result. 
Result so far: 181359.3
Subtract 1515 from 1740 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
The number 505 fits into 2250 4 times, leaving a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 181359.34
Subtract 2020 from 2250 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
When dividing 2300 by 505, we get 4 with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 181359.344
If we subtract 2020 from 2300, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 181359.344 with a balance of 0.028.
