Let's divide 86740975 by 88
The aim is to understand the frequency of 88 in 86740975.

On to step 1:
When dividing 8 by 88, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 88

Let's proceed to step 2:
86 divided by 88 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 88

Let's proceed to step 3:
88 goes into 867 9 times with a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 792 from 867 and we're left with 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 88

Let's proceed to step 4:
If we divide 754 by 88, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 704 away from 754, we end up with 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 88

On to step 5:
88 can be fit into 500 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 985.0
If we take 440 away from 500, we end up with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 88

Let's proceed to step 6:
88 can be fit into 609 6 times, resulting in a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 9856.0
Subtracting 528 from 609 leaves us with 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 88

Going ahead to step 7:
When dividing 817 by 88, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 98569.0
If we subtract 792 from 817, we get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 88

Advancing to step 8:
255 divided by 88 is 2 with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 985692.0
If we take 176 away from 255, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
88 can be fit into 790 8 times, resulting in a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 985692.8
Deduct 704 from 790 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 10:
The number 88 fits into 860 9 times, leaving a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 985692.89
The remainder is 68 after subtracting 792 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
680 divided by 88 is 7 with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 985692.897
The remainder is 64 after subtracting 616 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
If we divide 640 by 88, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 985692.8977
If we subtract 616 from 640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 985692.8977 with a remainder of 0.00024.
