309843 ÷ 88 
The aim is to understand the frequency of 88 in 309843.

Going ahead to step 1:
When dividing 3 by 88, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 88

Let's proceed to step 2:
88 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 88

Moving on to step 3:
When dividing 309 by 88, we get 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 264 from 309, we get 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 88

Advancing to step 4:
88 goes into 458 5 times with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 440 from 458, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 88

On to step 5:
184 divided by 88 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 352.0
Subtracting 176 from 184 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 88

Going ahead to step 6:
If we divide 83 by 88, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 3520.0
If we subtract 0 from 83, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 7:
When dividing 830 by 88, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 3520.9
If we subtract 792 from 830, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
88 goes into 380 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 3520.94
If we subtract 352 from 380, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 88, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3520.943
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 88, we get 1 with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 3520.9431
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
720 divided by 88 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3520.94318
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
160 divided by 88 is 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 3520.943181
The remainder is 72 after subtracting 88 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
If we divide 720 by 88, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3520.9431818
If we subtract 704 from 720, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
The number 88 fits into 160 1 times, leaving a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 3520.94318181
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 3520.94318181, with a leftover of 7.2e-08.
