780486 ÷ 88 
The aim is to understand the frequency of 88 in 780486.

Advancing to step 1:
If we divide 7 by 88, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 88

Going ahead to step 2:
When dividing 78 by 88, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 88

Let's proceed to step 3:
When dividing 780 by 88, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 76 after subtracting 704 from 780.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 88

Step 4:
88 goes into 764 8 times with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 60 after subtracting 704 from 764.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 88

Moving on to step 5:
When dividing 608 by 88, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 886.0
The remainder is 80 after subtracting 528 from 608.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 88

On to step 6:
806 divided by 88 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 8869.0
Deduct 792 from 806 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
When dividing 140 by 88, we get 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 8869.1
The remainder is 52 after subtracting 88 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
520 divided by 88 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 8869.15
Deduct 440 from 520 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
When dividing 800 by 88, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 8869.159
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 88, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 8869.159
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
88 can be fit into 800 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 8869.15909
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
88 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 8869.15909
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
The number 88 fits into 800 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 8869.1590909
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
When dividing 80 by 88, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 8869.1590909
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 8869.1590909 with a remaining 8e-08.
