47215844 ÷ 505 
The aim is to understand the frequency of 505 in 47215844.

On to step 1:
4 divided by 505 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 505

Let's proceed to step 2:
When dividing 47 by 505, we get 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 505

Advancing to step 3:
505 can be fit into 472 0 times, resulting in a remainder of 472.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 472 and we're left with 472.
Append the next digit (1) from the dividend to 472 and continue with: 4721 / 505

Going ahead to step 4:
The number 505 fits into 4721 9 times, leaving a remainder of 176.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 4545 from 4721 leaves us with 176.
Grab the next digit (5) from the dividend, add it to 176, then carry on: 1765 / 505

Moving on to step 5:
When dividing 1765 by 505, we get 3 with a remainder of 250.
The next digit of our result is 3. 
Result so far: 93.0
If we take 1515 away from 1765, we end up with 250.
Take the next digit (8) from the dividend and append it to 250, then repeat: 2508 / 505

Step 6:
505 can be fit into 2508 4 times, resulting in a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 934.0
If we take 2020 away from 2508, we end up with 488.
Include the next digit (4) from the dividend after 488, then repeat: 4884 / 505

Step 7:
When dividing 4884 by 505, we get 9 with a remainder of 339.
Put 9 as the next digit of the answer. 
Result so far: 9349.0
Subtract 4545 from 4884 to get 339.
Append the next digit (4) from the dividend to 339 and continue with: 3394 / 505

Advancing to step 8:
If we divide 3394 by 505, we get 6 and a remainder of 364.
The next digit of our result is 6. 
Result so far: 93496.0
The remainder is 364 after subtracting 3030 from 3394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 9:
When dividing 3640 by 505, we get 7 with a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 93496.7
Subtracting 3535 from 3640 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.

Moving on to step 10:
1050 divided by 505 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 93496.72
If we subtract 1010 from 1050, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 505 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 93496.72
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.

Advancing to step 12:
4000 divided by 505 is 7 with a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 93496.7207
Deduct 3535 from 4000 and we're left 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.

Step 13:
The number 505 fits into 4650 9 times, leaving a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 93496.72079
The remainder is 105 after subtracting 4545 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 14:
If we divide 1050 by 505, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 93496.720792
The remainder is 40 after subtracting 1010 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
505 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 93496.720792
Subtract 0 from 400 to 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 16:
505 can be fit into 4000 7 times, resulting in a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 93496.72079207
Deduct 3535 from 4000 and we're left 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.

After the division, we end up with 93496.72079207 and a remainder of 4.65e-07.
