We look at the division of 349664 by 88 
The aim is to understand the frequency of 88 in 349664.

Step 1:
If we divide 3 by 88, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 88

Moving on to step 2:
The number 88 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 88

Let's proceed to step 3:
88 goes into 349 3 times with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 264 away from 349, we end up with 85.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 88

Step 4:
The number 88 fits into 856 9 times, leaving a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 64 after subtracting 792 from 856.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 88

Going ahead to step 5:
When dividing 646 by 88, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 397.0
Deduct 616 from 646 and we're left with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 88

Moving on to step 6:
88 can be fit into 304 3 times, resulting in a remainder of 40.
The next digit of our result is 3. 
Result so far: 3973.0
Subtract 264 from 304 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
400 divided by 88 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 3973.4
Deduct 352 from 400 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
88 can be fit into 480 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 3973.45
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
400 divided by 88 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 3973.454
Subtracting 352 from 400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
If we divide 480 by 88, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 3973.4545
If we take 440 away from 480, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
88 goes into 400 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 3973.45454
Deduct 352 from 400 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
88 goes into 480 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 3973.454545
Subtracting 440 from 480 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
88 can be fit into 400 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 3973.4545454
Deduct 352 from 400 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
480 divided by 88 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 3973.45454545
Subtract 440 from 480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 3973.45454545 with a balance of 4e-08.
