Let's divide 2526255 by 816
The aim is to understand the frequency of 816 in 2526255.

Going ahead to step 1:
If we divide 2 by 816, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 816

Advancing to step 2:
25 divided by 816 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 816

Step 3:
If we divide 252 by 816, we get 0 and a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 252, we get 252.
Append the next digit (6) from the dividend to 252 and continue with: 2526 / 816

Going ahead to step 4:
The number 816 fits into 2526 3 times, leaving a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2448 from 2526 and we're left with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 816

Going ahead to step 5:
816 goes into 782 0 times with a remainder of 782.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 782 leaves us with 782.
Include the next digit (5) from the dividend after 782, then repeat: 7825 / 816

Advancing to step 6:
If we divide 7825 by 816, we get 9 and a remainder of 481.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Subtracting 7344 from 7825 leaves us with 481.
Fetch the next digit (5) from the dividend, attach it to 481 and continue: 4815 / 816

Step 7:
When dividing 4815 by 816, we get 5 with a remainder of 735.
Use 5 as the next digit of our solution. 
Result so far: 3095.0
Deduct 4080 from 4815 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Advancing to step 8:
The number 816 fits into 7350 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 3095.9
Subtract 7344 from 7350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
60 divided by 816 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3095.9
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 816, we get 0 and a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 3095.9
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 3095.9, with a leftover of 0.06.
