Let's divide 87169 by 88
The aim is to understand the frequency of 88 in 87169.

On to step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 88

On to step 2:
The number 88 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 88

Going ahead to step 3:
871 divided by 88 is 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 792 from 871 to get 79.
Bring next digit (6) of the dividend behind the 79 and repeat the process: 796 / 88

Going ahead to step 4:
796 divided by 88 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 4 after subtracting 792 from 796.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 88

Step 5:
If we divide 49 by 88, we get 0 and a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 990.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 6:
The number 88 fits into 490 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 990.5
The remainder is 50 after subtracting 440 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
88 goes into 500 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 990.55
If we take 440 away from 500, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 990.55 with a remainder of 0.06.
