We look at the division of 861725 by 88 
The aim is to understand the frequency of 88 in 861725.

Going ahead to step 1:
The number 88 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 88

On to step 2:
88 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 88

Step 3:
The number 88 fits into 861 9 times, leaving a remainder of 69.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 792 from 861 and we're left with 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 88

On to step 4:
When dividing 697 by 88, we get 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 81 after subtracting 616 from 697.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 88

Let's proceed to step 5:
88 goes into 812 9 times with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 979.0
Subtract 792 from 812 to get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 88

Advancing to step 6:
88 can be fit into 205 2 times, resulting in a remainder of 29.
The next digit of our result is 2. 
Result so far: 9792.0
The remainder is 29 after subtracting 176 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
88 can be fit into 290 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 9792.3
If we subtract 264 from 290, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
When dividing 260 by 88, we get 2 with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 9792.32
Subtract 176 from 260 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 9:
When dividing 840 by 88, we get 9 with a remainder of 48.
The next digit of our result is 9. 
Result so far: 9792.329
The remainder is 48 after subtracting 792 from 840.
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 10:
88 goes into 480 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 9792.3295
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.

On to step 11:
88 goes into 400 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 9792.32954
If we subtract 352 from 400, we get 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 12:
88 goes into 480 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9792.329545
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.

Let's proceed to step 13:
If we divide 400 by 88, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 9792.3295454
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.

Moving on to step 14:
When dividing 480 by 88, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 9792.32954545
The remainder is 40 after subtracting 440 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 9792.32954545, and the remainder is 4e-08.
