81740644 divided by 506 
The aim is to understand the frequency of 506 in 81740644.

Advancing to step 1:
The number 506 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 506

Moving on to step 2:
When dividing 81 by 506, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 506

Advancing to step 3:
When dividing 817 by 506, we get 1 with a remainder of 311.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 506 from 817, we get 311.
Grab the next digit (4) from the dividend, add it to 311, then carry on: 3114 / 506

Moving on to step 4:
When dividing 3114 by 506, we get 6 with a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 3036 away from 3114, we end up with 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 506

On to step 5:
506 goes into 780 1 times with a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Deduct 506 from 780 and we're left with 274.
Bring next digit (6) of the dividend behind the 274 and repeat the process: 2746 / 506

Moving on to step 6:
The number 506 fits into 2746 5 times, leaving a remainder of 216.
The number 5 becomes the next digit in our result. 
Result so far: 1615.0
If we subtract 2530 from 2746, we get 216.
Fetch the next digit (4) from the dividend, attach it to 216 and continue: 2164 / 506

Advancing to step 7:
2164 divided by 506 is 4 with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 16154.0
Subtract 2024 from 2164 to get 140.
Fetch the next digit (4) from the dividend, attach it to 140 and continue: 1404 / 506

Advancing to step 8:
If we divide 1404 by 506, we get 2 and a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 161542.0
Subtract 1012 from 1404 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 9:
The number 506 fits into 3920 7 times, leaving a remainder of 378.
The number 7 becomes the next digit in our result. 
Result so far: 161542.7
Deduct 3542 from 3920 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 10:
When dividing 3780 by 506, we get 7 with a remainder of 238.
Write down 7 as next digit of the result. 
Result so far: 161542.77
If we subtract 3542 from 3780, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

In conclusion, the division gives 161542.77 with a balance of 0.238.
