Let's divide 643117 by 88
The aim is to understand the frequency of 88 in 643117.

On to step 1:
When dividing 6 by 88, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 88

Let's proceed to step 2:
64 divided by 88 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 88

Advancing to step 3:
88 can be fit into 643 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 616 from 643 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 88

Moving on to step 4:
271 divided by 88 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtract 264 from 271 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 88

Going ahead to step 5:
88 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 730.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 88

Advancing to step 6:
717 divided by 88 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 7308.0
Subtract 704 from 717 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 88, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 7308.1
Subtract 88 from 130 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
88 can be fit into 420 4 times, resulting in a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 7308.14
Subtract 352 from 420 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
When dividing 680 by 88, we get 7 with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 7308.147
If we subtract 616 from 680, we 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.

Advancing to step 10:
88 goes into 640 7 times with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 7308.1477
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 7308.1477 and a remainder of 0.00024.
