81460819 divided by 505 
The aim is to understand the frequency of 505 in 81460819.

Advancing to step 1:
If we divide 8 by 505, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 505

Advancing to step 2:
If we divide 81 by 505, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 505

Going ahead to step 3:
When dividing 814 by 505, we get 1 with a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 309 after subtracting 505 from 814.
Take the next digit (6) from the dividend and append it to 309, then repeat: 3096 / 505

Going ahead to step 4:
3096 divided by 505 is 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 3030 from 3096 and we're left with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 505

Advancing to step 5:
505 can be fit into 660 1 times, resulting in a remainder of 155.
Write down 1 as next digit of the result. 
Result so far: 161.0
If we subtract 505 from 660, we get 155.
Fetch the next digit (8) from the dividend, attach it to 155 and continue: 1558 / 505

On to step 6:
If we divide 1558 by 505, we get 3 and a remainder of 43.
The next digit of our result is 3. 
Result so far: 1613.0
Subtract 1515 from 1558 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 505

Going ahead to step 7:
When dividing 431 by 505, we get 0 with a remainder of 431.
Put 0 as the next digit of the answer. 
Result so far: 16130.0
If we take 0 away from 431, we end up with 431.
Append the next digit (9) from the dividend to 431 and continue with: 4319 / 505

Let's proceed to step 8:
When dividing 4319 by 505, we get 8 with a remainder of 279.
The next digit of our result is 8. 
Result so far: 161308.0
Subtract 4040 from 4319 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 9:
505 goes into 2790 5 times with a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 161308.5
Subtract 2525 from 2790 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 10:
505 goes into 2650 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 161308.55
Subtract 2525 from 2650 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

In conclusion, the division gives 161308.55 with a balance of 0.125.
