We look at the division of 18888321 by 275 
The aim is to understand the frequency of 275 in 18888321.

Advancing to step 1:
1 divided by 275 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 275

Let's proceed to step 2:
275 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 275

Advancing to step 3:
If we divide 188 by 275, we get 0 and a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 275

Moving on to step 4:
If we divide 1888 by 275, we get 6 and a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 1650 from 1888 and we're left with 238.
Append the next digit (8) from the dividend to 238 and continue with: 2388 / 275

Step 5:
2388 divided by 275 is 8 with a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtract 2200 from 2388 to get 188.
Fetch the next digit (3) from the dividend, attach it to 188 and continue: 1883 / 275

On to step 6:
If we divide 1883 by 275, we get 6 and a remainder of 233.
Record the quotient 6 as the next digit in the result. 
Result so far: 686.0
Subtract 1650 from 1883 to get 233.
Include the next digit (2) from the dividend after 233, then repeat: 2332 / 275

Let's proceed to step 7:
If we divide 2332 by 275, we get 8 and a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 6868.0
Subtracting 2200 from 2332 leaves us with 132.
Bring next digit (1) of the dividend behind the 132 and repeat the process: 1321 / 275

Going ahead to step 8:
When dividing 1321 by 275, we get 4 with a remainder of 221.
The number 4 becomes the next digit in our result. 
Result so far: 68684.0
The remainder is 221 after subtracting 1100 from 1321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
The number 275 fits into 2210 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 68684.8
Subtract 2200 from 2210 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 275 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 68684.8
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
275 goes into 1000 3 times with a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 68684.803
Deduct 825 from 1000 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
1750 divided by 275 is 6 with a remainder of 100.
The number 6 becomes the next digit in our result. 
Result so far: 68684.8036
Deduct 1650 from 1750 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
1000 divided by 275 is 3 with a remainder of 175.
The next digit of our result is 3. 
Result so far: 68684.80363
Deduct 825 from 1000 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 14:
If we divide 1750 by 275, we get 6 and a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 68684.803636
Subtracting 1650 from 1750 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
The number 275 fits into 1000 3 times, leaving a remainder of 175.
The next digit of our result is 3. 
Result so far: 68684.8036363
If we take 825 away from 1000, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 16:
The number 275 fits into 1750 6 times, leaving a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 68684.80363636
Subtracting 1650 from 1750 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 68684.80363636, and the remainder is 1e-07.
