We're dividing 274129 by 88 
The aim is to understand the frequency of 88 in 274129.

Advancing to step 1:
The number 88 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 88

On to step 2:
When dividing 27 by 88, we get 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 88

Going ahead to step 3:
88 goes into 274 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 264 from 274, we get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 88

Going ahead to step 4:
If we divide 101 by 88, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 13 after subtracting 88 from 101.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 88

Step 5:
132 divided by 88 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 311.0
Subtracting 88 from 132 leaves us with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 88

Advancing to step 6:
The number 88 fits into 449 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 3115.0
Deduct 440 from 449 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 88, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 3115.1
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 88 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3115.1
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
88 goes into 200 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3115.102
The remainder is 24 after subtracting 176 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
The number 88 fits into 240 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 3115.1022
Subtract 176 from 240 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 3115.1022 with a remainder of 0.00064.
