68679369 divided by 505 
The aim is to understand the frequency of 505 in 68679369.

Let's proceed to step 1:
The number 505 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 505

Moving on to step 2:
505 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 505

On to step 3:
If we divide 686 by 505, we get 1 and a remainder of 181.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 181 after subtracting 505 from 686.
Fetch the next digit (7) from the dividend, attach it to 181 and continue: 1817 / 505

On to step 4:
505 goes into 1817 3 times with a remainder of 302.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1515 from 1817 to get 302.
Bring next digit (9) of the dividend behind the 302 and repeat the process: 3029 / 505

On to step 5:
505 can be fit into 3029 5 times, resulting in a remainder of 504.
The next digit of our result is 5. 
Result so far: 135.0
The remainder is 504 after subtracting 2525 from 3029.
Include the next digit (3) from the dividend after 504, then repeat: 5043 / 505

Moving on to step 6:
505 goes into 5043 9 times with a remainder of 498.
Use 9 as the next digit of our solution. 
Result so far: 1359.0
If we take 4545 away from 5043, we end up with 498.
Grab the next digit (6) from the dividend, add it to 498, then carry on: 4986 / 505

Let's proceed to step 7:
505 can be fit into 4986 9 times, resulting in a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 13599.0
Deduct 4545 from 4986 and we're left with 441.
Take the next digit (9) from the dividend and append it to 441, then repeat: 4419 / 505

Advancing to step 8:
The number 505 fits into 4419 8 times, leaving a remainder of 379.
Put 8 as the next digit of the answer. 
Result so far: 135998.0
If we subtract 4040 from 4419, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 9:
The number 505 fits into 3790 7 times, leaving a remainder of 255.
Put 7 as the next digit of the answer. 
Result so far: 135998.7
If we subtract 3535 from 3790, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 10:
If we divide 2550 by 505, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 135998.75
Subtracting 2525 from 2550 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 505, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 135998.75
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
2500 divided by 505 is 4 with a remainder of 480.
Use 4 as the next digit of our solution. 
Result so far: 135998.7504
If we take 2020 away from 2500, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
505 goes into 4800 9 times with a remainder of 255.
The number 9 becomes the next digit in our result. 
Result so far: 135998.75049
The remainder is 255 after subtracting 4545 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 14:
The number 505 fits into 2550 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 135998.750495
The remainder is 25 after subtracting 2525 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 15:
250 divided by 505 is 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 135998.750495
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 16:
When dividing 2500 by 505, we get 4 with a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 135998.75049504
If we take 2020 away from 2500, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 135998.75049504 with a remainder of 4.8e-07.
