We look at the division of 52817141 by 268 
The aim is to understand the frequency of 268 in 52817141.

On to step 1:
When dividing 5 by 268, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 268

Going ahead to step 2:
268 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 268

On to step 3:
When dividing 528 by 268, we get 1 with a remainder of 260.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 268 from 528 and we're left with 260.
Bring next digit (1) of the dividend behind the 260 and repeat the process: 2601 / 268

Moving on to step 4:
When dividing 2601 by 268, we get 9 with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 2412 from 2601 and we're left with 189.
Take the next digit (7) from the dividend and append it to 189, then repeat: 1897 / 268

Let's proceed to step 5:
The number 268 fits into 1897 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtracting 1876 from 1897 leaves us with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 268

On to step 6:
When dividing 211 by 268, we get 0 with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
Subtract 0 from 211 to get 211.
Fetch the next digit (4) from the dividend, attach it to 211 and continue: 2114 / 268

Going ahead to step 7:
268 can be fit into 2114 7 times, resulting in a remainder of 238.
The number 7 becomes the next digit in our result. 
Result so far: 19707.0
Deduct 1876 from 2114 and we're left with 238.
Grab the next digit (1) from the dividend, add it to 238, then carry on: 2381 / 268

Let's proceed to step 8:
When dividing 2381 by 268, we get 8 with a remainder of 237.
The next digit of our result is 8. 
Result so far: 197078.0
Deduct 2144 from 2381 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 9:
268 goes into 2370 8 times with a remainder of 226.
The next digit of our result is 8. 
Result so far: 197078.8
Subtract 2144 from 2370 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
If we divide 2260 by 268, we get 8 and a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 197078.88
Deduct 2144 from 2260 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final result is 197078.88 with a remainder of 0.116.
