We look at the division of 25252818 by 627 
The aim is to understand the frequency of 627 in 25252818.

Advancing to step 1:
If we divide 2 by 627, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 627

Advancing to step 2:
If we divide 25 by 627, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 627

Step 3:
If we divide 252 by 627, we get 0 and a remainder of 252.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 252 after subtracting 0 from 252.
Bring next digit (5) of the dividend behind the 252 and repeat the process: 2525 / 627

On to step 4:
The number 627 fits into 2525 4 times, leaving a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 17 after subtracting 2508 from 2525.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 627

Moving on to step 5:
If we divide 172 by 627, we get 0 and a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtracting 0 from 172 leaves us with 172.
Grab the next digit (8) from the dividend, add it to 172, then carry on: 1728 / 627

Moving on to step 6:
When dividing 1728 by 627, we get 2 with a remainder of 474.
Write down 2 as next digit of the result. 
Result so far: 402.0
Subtract 1254 from 1728 to get 474.
Append the next digit (1) from the dividend to 474 and continue with: 4741 / 627

Step 7:
4741 divided by 627 is 7 with a remainder of 352.
The number 7 becomes the next digit in our result. 
Result so far: 4027.0
Deduct 4389 from 4741 and we're left with 352.
Bring next digit (8) of the dividend behind the 352 and repeat the process: 3528 / 627

Moving on to step 8:
3528 divided by 627 is 5 with a remainder of 393.
Put 5 as the next digit of the answer. 
Result so far: 40275.0
Subtract 3135 from 3528 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 9:
3930 divided by 627 is 6 with a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 40275.6
Subtract 3762 from 3930 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
1680 divided by 627 is 2 with a remainder of 426.
Write down 2 as next digit of the result. 
Result so far: 40275.62
Subtract 1254 from 1680 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 11:
The number 627 fits into 4260 6 times, leaving a remainder of 498.
The number 6 becomes the next digit in our result. 
Result so far: 40275.626
Deduct 3762 from 4260 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 12:
627 can be fit into 4980 7 times, resulting in a remainder of 591.
The next digit of our result is 7. 
Result so far: 40275.6267
Subtract 4389 from 4980 to get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Step 13:
The number 627 fits into 5910 9 times, leaving a remainder of 267.
Use 9 as the next digit of our solution. 
Result so far: 40275.62679
Deduct 5643 from 5910 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 14:
627 goes into 2670 4 times with a remainder of 162.
Record the quotient 4 as the next digit in the result. 
Result so far: 40275.626794
The remainder is 162 after subtracting 2508 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 15:
When dividing 1620 by 627, we get 2 with a remainder of 366.
Put 2 as the next digit of the answer. 
Result so far: 40275.6267942
Deduct 1254 from 1620 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 16:
If we divide 3660 by 627, we get 5 and a remainder of 525.
Write down 5 as next digit of the result. 
Result so far: 40275.62679425
If we subtract 3135 from 3660, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The final outcome is 40275.62679425, with a leftover of 5.25e-07.
