We're dividing 68751540 by 508 
The aim is to understand the frequency of 508 in 68751540.

Let's proceed to step 1:
508 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 508

Going ahead to step 2:
508 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 508

Going ahead to step 3:
If we divide 687 by 508, we get 1 and a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 508 away from 687, we end up with 179.
Take the next digit (5) from the dividend and append it to 179, then repeat: 1795 / 508

On to step 4:
1795 divided by 508 is 3 with a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1524 from 1795 leaves us with 271.
Bring next digit (1) of the dividend behind the 271 and repeat the process: 2711 / 508

Moving on to step 5:
508 goes into 2711 5 times with a remainder of 171.
The next digit of our result is 5. 
Result so far: 135.0
If we subtract 2540 from 2711, we get 171.
Take the next digit (5) from the dividend and append it to 171, then repeat: 1715 / 508

Moving on to step 6:
1715 divided by 508 is 3 with a remainder of 191.
Use 3 as the next digit of our solution. 
Result so far: 1353.0
The remainder is 191 after subtracting 1524 from 1715.
Include the next digit (4) from the dividend after 191, then repeat: 1914 / 508

Advancing to step 7:
When dividing 1914 by 508, we get 3 with a remainder of 390.
Put 3 as the next digit of the answer. 
Result so far: 13533.0
Deduct 1524 from 1914 and we're left with 390.
Take the next digit (0) from the dividend and append it to 390, then repeat: 3900 / 508

Step 8:
3900 divided by 508 is 7 with a remainder of 344.
Put 7 as the next digit of the answer. 
Result so far: 135337.0
If we subtract 3556 from 3900, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 9:
508 goes into 3440 6 times with a remainder of 392.
The next digit of our result is 6. 
Result so far: 135337.6
If we subtract 3048 from 3440, we 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.

On to step 10:
The number 508 fits into 3920 7 times, leaving a remainder of 364.
Record the quotient 7 as the next digit in the result. 
Result so far: 135337.67
Subtracting 3556 from 3920 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 11:
When dividing 3640 by 508, we get 7 with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 135337.677
If we take 3556 away from 3640, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 135337.677 and a remainder of 0.0084.
