We divide 87698052 by 508
The aim is to understand the frequency of 508 in 87698052.

Going ahead to step 1:
8 divided by 508 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 508

Let's proceed to step 2:
87 divided by 508 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 508

Step 3:
508 goes into 876 1 times with a remainder of 368.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 508 from 876 to get 368.
Bring next digit (9) of the dividend behind the 368 and repeat the process: 3689 / 508

On to step 4:
3689 divided by 508 is 7 with a remainder of 133.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3556 from 3689 to get 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 508

Step 5:
If we divide 1338 by 508, we get 2 and a remainder of 322.
The next digit of our result is 2. 
Result so far: 172.0
If we subtract 1016 from 1338, we get 322.
Bring next digit (0) of the dividend behind the 322 and repeat the process: 3220 / 508

On to step 6:
If we divide 3220 by 508, we get 6 and a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 1726.0
Subtract 3048 from 3220 to get 172.
Include the next digit (5) from the dividend after 172, then repeat: 1725 / 508

On to step 7:
1725 divided by 508 is 3 with a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 17263.0
If we subtract 1524 from 1725, we get 201.
Fetch the next digit (2) from the dividend, attach it to 201 and continue: 2012 / 508

Step 8:
508 can be fit into 2012 3 times, resulting in a remainder of 488.
Use 3 as the next digit of our solution. 
Result so far: 172633.0
Deduct 1524 from 2012 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 9:
If we divide 4880 by 508, we get 9 and a remainder of 308.
The number 9 becomes the next digit in our result. 
Result so far: 172633.9
Subtract 4572 from 4880 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 10:
508 can be fit into 3080 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 172633.96
If we subtract 3048 from 3080, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
If we divide 320 by 508, we get 0 and a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 172633.96
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
If we divide 3200 by 508, we get 6 and a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 172633.9606
If we take 3048 away from 3200, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 13:
1520 divided by 508 is 2 with a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 172633.96062
Subtracting 1016 from 1520 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 14:
5040 divided by 508 is 9 with a remainder of 468.
Record the quotient 9 as the next digit in the result. 
Result so far: 172633.960629
Subtract 4572 from 5040 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 15:
When dividing 4680 by 508, we get 9 with a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 172633.9606299
Subtracting 4572 from 4680 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 172633.9606299 and a remainder of 1.08e-06.
