Let's divide 78565983 by 508
The aim is to understand the frequency of 508 in 78565983.

Let's proceed to step 1:
If we divide 7 by 508, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 508

Step 2:
If we divide 78 by 508, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 508

Let's proceed to step 3:
508 can be fit into 785 1 times, resulting in a remainder of 277.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 508 from 785, we get 277.
Take the next digit (6) from the dividend and append it to 277, then repeat: 2776 / 508

Step 4:
If we divide 2776 by 508, we get 5 and a remainder of 236.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2540 from 2776 to get 236.
Append the next digit (5) from the dividend to 236 and continue with: 2365 / 508

Going ahead to step 5:
The number 508 fits into 2365 4 times, leaving a remainder of 333.
Put 4 as the next digit of the answer. 
Result so far: 154.0
The remainder is 333 after subtracting 2032 from 2365.
Include the next digit (9) from the dividend after 333, then repeat: 3339 / 508

Moving on to step 6:
508 can be fit into 3339 6 times, resulting in a remainder of 291.
The next digit of our result is 6. 
Result so far: 1546.0
Subtracting 3048 from 3339 leaves us with 291.
Include the next digit (8) from the dividend after 291, then repeat: 2918 / 508

Let's proceed to step 7:
508 can be fit into 2918 5 times, resulting in a remainder of 378.
Write down 5 as next digit of the result. 
Result so far: 15465.0
Subtract 2540 from 2918 to get 378.
Append the next digit (3) from the dividend to 378 and continue with: 3783 / 508

Step 8:
508 can be fit into 3783 7 times, resulting in a remainder of 227.
Write down 7 as next digit of the result. 
Result so far: 154657.0
The remainder is 227 after subtracting 3556 from 3783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 9:
508 can be fit into 2270 4 times, resulting in a remainder of 238.
Put 4 as the next digit of the answer. 
Result so far: 154657.4
If we subtract 2032 from 2270, 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.

Let's proceed to step 10:
2380 divided by 508 is 4 with a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 154657.44
Deduct 2032 from 2380 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final outcome is 154657.44, with a leftover of 0.348.
