Let's divide 102921 by 88
The aim is to understand the frequency of 88 in 102921.

Going ahead to step 1:
When dividing 1 by 88, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 88

Step 2:
If we divide 10 by 88, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 88

Moving on to step 3:
88 can be fit into 102 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 88 from 102, we get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 88

On to step 4:
If we divide 149 by 88, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 88 from 149, we get 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 88

Let's proceed to step 5:
When dividing 612 by 88, we get 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 528 from 612 and we're left with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 88

Step 6:
841 divided by 88 is 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 1169.0
If we subtract 792 from 841, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
When dividing 490 by 88, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1169.5
Subtracting 440 from 490 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
88 can be fit into 500 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 1169.55
Subtract 440 from 500 to get 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 1169.55 with a remainder of 0.06.
