55507193 ÷ 505 
The aim is to understand the frequency of 505 in 55507193.

Let's proceed to step 1:
5 divided by 505 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 505

Moving on to step 2:
55 divided by 505 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (5) from the dividend to 55 and continue with: 555 / 505

Advancing to step 3:
If we divide 555 by 505, we get 1 and a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 505 from 555, we get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 505

On to step 4:
500 divided by 505 is 0 with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 500 after subtracting 0 from 500.
Take the next digit (7) from the dividend and append it to 500, then repeat: 5007 / 505

Step 5:
5007 divided by 505 is 9 with a remainder of 462.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 4545 from 5007, we get 462.
Take the next digit (1) from the dividend and append it to 462, then repeat: 4621 / 505

Advancing to step 6:
If we divide 4621 by 505, we get 9 and a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 1099.0
If we subtract 4545 from 4621, we get 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 505

Advancing to step 7:
If we divide 769 by 505, we get 1 and a remainder of 264.
The next digit of our result is 1. 
Result so far: 10991.0
Deduct 505 from 769 and we're left with 264.
Include the next digit (3) from the dividend after 264, then repeat: 2643 / 505

Moving on to step 8:
505 goes into 2643 5 times with a remainder of 118.
Record the quotient 5 as the next digit in the result. 
Result so far: 109915.0
The remainder is 118 after subtracting 2525 from 2643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
1180 divided by 505 is 2 with a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 109915.2
Deduct 1010 from 1180 and we're left 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.

Step 10:
1700 divided by 505 is 3 with a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 109915.23
If we subtract 1515 from 1700, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 11:
1850 divided by 505 is 3 with a remainder of 335.
The number 3 becomes the next digit in our result. 
Result so far: 109915.233
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.

The final result is 109915.233 with a remainder of 0.0335.
