We divide 35215399 by 275
The aim is to understand the frequency of 275 in 35215399.

Moving on to step 1:
3 divided by 275 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 275

Step 2:
When dividing 35 by 275, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 275

Moving on to step 3:
352 divided by 275 is 1 with a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 275 away from 352, we end up with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 275

Advancing to step 4:
If we divide 771 by 275, we get 2 and a remainder of 221.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 550 from 771 to get 221.
Include the next digit (5) from the dividend after 221, then repeat: 2215 / 275

On to step 5:
The number 275 fits into 2215 8 times, leaving a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 2200 from 2215 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 275

Let's proceed to step 6:
If we divide 153 by 275, we get 0 and a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 1280.0
The remainder is 153 after subtracting 0 from 153.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 275

Advancing to step 7:
If we divide 1539 by 275, we get 5 and a remainder of 164.
The next digit of our result is 5. 
Result so far: 12805.0
If we take 1375 away from 1539, we end up with 164.
Fetch the next digit (9) from the dividend, attach it to 164 and continue: 1649 / 275

On to step 8:
275 can be fit into 1649 5 times, resulting in a remainder of 274.
Record the quotient 5 as the next digit in the result. 
Result so far: 128055.0
Deduct 1375 from 1649 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
The number 275 fits into 2740 9 times, leaving a remainder of 265.
The number 9 becomes the next digit in our result. 
Result so far: 128055.9
Subtract 2475 from 2740 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 10:
275 can be fit into 2650 9 times, resulting in a remainder of 175.
The number 9 becomes the next digit in our result. 
Result so far: 128055.99
Deduct 2475 from 2650 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.

After the division, we end up with 128055.99 and a remainder of 0.175.
