86885717 divided by 508 
The aim is to understand the frequency of 508 in 86885717.

Step 1:
If we divide 8 by 508, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 508

Going ahead to step 2:
508 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 508

Moving on to step 3:
508 goes into 868 1 times with a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 508 from 868 to get 360.
Grab the next digit (8) from the dividend, add it to 360, then carry on: 3608 / 508

Step 4:
If we divide 3608 by 508, we get 7 and a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 3556 away from 3608, we end up with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 508

Moving on to step 5:
508 goes into 525 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 508 from 525 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 508

Step 6:
508 can be fit into 177 0 times, resulting in a remainder of 177.
The next digit of our result is 0. 
Result so far: 1710.0
The remainder is 177 after subtracting 0 from 177.
Fetch the next digit (1) from the dividend, attach it to 177 and continue: 1771 / 508

Advancing to step 7:
If we divide 1771 by 508, we get 3 and a remainder of 247.
Record the quotient 3 as the next digit in the result. 
Result so far: 17103.0
If we subtract 1524 from 1771, we get 247.
Include the next digit (7) from the dividend after 247, then repeat: 2477 / 508

Let's proceed to step 8:
2477 divided by 508 is 4 with a remainder of 445.
Use 4 as the next digit of our solution. 
Result so far: 171034.0
Subtracting 2032 from 2477 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
508 can be fit into 4450 8 times, resulting in a remainder of 386.
Write down 8 as next digit of the result. 
Result so far: 171034.8
If we subtract 4064 from 4450, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 10:
The number 508 fits into 3860 7 times, leaving a remainder of 304.
Record the quotient 7 as the next digit in the result. 
Result so far: 171034.87
If we take 3556 away from 3860, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
The number 508 fits into 3040 5 times, leaving a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 171034.875
Subtract 2540 from 3040 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
508 can be fit into 5000 9 times, resulting in a remainder of 428.
Put 9 as the next digit of the answer. 
Result so far: 171034.8759
Subtract 4572 from 5000 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 13:
508 can be fit into 4280 8 times, resulting in a remainder of 216.
The next digit of our result is 8. 
Result so far: 171034.87598
If we take 4064 away from 4280, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
When dividing 2160 by 508, we get 4 with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 171034.875984
If we subtract 2032 from 2160, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 15:
508 goes into 1280 2 times with a remainder of 264.
Use 2 as the next digit of our solution. 
Result so far: 171034.8759842
Subtract 1016 from 1280 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 16:
The number 508 fits into 2640 5 times, leaving a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 171034.87598425
Subtracting 2540 from 2640 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 171034.87598425 with a balance of 1e-07.
