We look at the division of 11102902 by 532 
The aim is to understand the frequency of 532 in 11102902.

Advancing to step 1:
The number 532 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 532

Moving on to step 2:
532 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 532

Let's proceed to step 3:
111 divided by 532 is 0 with a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 111, we end up with 111.
Grab the next digit (0) from the dividend, add it to 111, then carry on: 1110 / 532

On to step 4:
If we divide 1110 by 532, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 46 after subtracting 1064 from 1110.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 532

Step 5:
The number 532 fits into 462 0 times, leaving a remainder of 462.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 462 to get 462.
Take the next digit (9) from the dividend and append it to 462, then repeat: 4629 / 532

Going ahead to step 6:
The number 532 fits into 4629 8 times, leaving a remainder of 373.
Use 8 as the next digit of our solution. 
Result so far: 208.0
The remainder is 373 after subtracting 4256 from 4629.
Include the next digit (0) from the dividend after 373, then repeat: 3730 / 532

On to step 7:
When dividing 3730 by 532, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2087.0
Subtract 3724 from 3730 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 532

Going ahead to step 8:
532 can be fit into 62 0 times, resulting in a remainder of 62.
The next digit of our result is 0. 
Result so far: 20870.0
If we subtract 0 from 62, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
532 goes into 620 1 times with a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 20870.1
Subtracting 532 from 620 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
If we divide 880 by 532, we get 1 and a remainder of 348.
Write down 1 as next digit of the result. 
Result so far: 20870.11
Subtracting 532 from 880 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Our division results in 20870.11 with a remaining 0.348.
