Let's divide 99093630 by 538
The aim is to understand the frequency of 538 in 99093630.

Step 1:
9 divided by 538 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 538

Going ahead to step 2:
538 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 538

Going ahead to step 3:
The number 538 fits into 990 1 times, leaving a remainder of 452.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 452 after subtracting 538 from 990.
Append the next digit (9) from the dividend to 452 and continue with: 4529 / 538

Moving on to step 4:
If we divide 4529 by 538, we get 8 and a remainder of 225.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 4304 from 4529 to get 225.
Take the next digit (3) from the dividend and append it to 225, then repeat: 2253 / 538

On to step 5:
If we divide 2253 by 538, we get 4 and a remainder of 101.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Subtract 2152 from 2253 to get 101.
Fetch the next digit (6) from the dividend, attach it to 101 and continue: 1016 / 538

Moving on to step 6:
1016 divided by 538 is 1 with a remainder of 478.
Write down 1 as next digit of the result. 
Result so far: 1841.0
Subtracting 538 from 1016 leaves us with 478.
Take the next digit (3) from the dividend and append it to 478, then repeat: 4783 / 538

Advancing to step 7:
The number 538 fits into 4783 8 times, leaving a remainder of 479.
Use 8 as the next digit of our solution. 
Result so far: 18418.0
If we take 4304 away from 4783, we end up with 479.
Include the next digit (0) from the dividend after 479, then repeat: 4790 / 538

Moving on to step 8:
If we divide 4790 by 538, we get 8 and a remainder of 486.
The number 8 becomes the next digit in our result. 
Result so far: 184188.0
Subtract 4304 from 4790 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 9:
When dividing 4860 by 538, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 184188.9
If we subtract 4842 from 4860, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
538 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 184188.9
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
538 can be fit into 1800 3 times, resulting in a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 184188.903
Subtracting 1614 from 1800 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 12:
538 goes into 1860 3 times with a remainder of 246.
Write down 3 as next digit of the result. 
Result so far: 184188.9033
If we subtract 1614 from 1860, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

After the division, we end up with 184188.9033 and a remainder of 0.00246.
