Let's divide 23523430 by 538
The aim is to understand the frequency of 538 in 23523430.

Advancing to step 1:
The number 538 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 538

Let's proceed to step 2:
When dividing 23 by 538, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 538

Going ahead to step 3:
If we divide 235 by 538, we get 0 and a remainder of 235.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 235, we get 235.
Bring next digit (2) of the dividend behind the 235 and repeat the process: 2352 / 538

Advancing to step 4:
The number 538 fits into 2352 4 times, leaving a remainder of 200.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2152 from 2352, we get 200.
Bring next digit (3) of the dividend behind the 200 and repeat the process: 2003 / 538

On to step 5:
2003 divided by 538 is 3 with a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 1614 from 2003 and we're left with 389.
Append the next digit (4) from the dividend to 389 and continue with: 3894 / 538

Advancing to step 6:
When dividing 3894 by 538, we get 7 with a remainder of 128.
Put 7 as the next digit of the answer. 
Result so far: 437.0
Subtracting 3766 from 3894 leaves us with 128.
Take the next digit (3) from the dividend and append it to 128, then repeat: 1283 / 538

Moving on to step 7:
538 goes into 1283 2 times with a remainder of 207.
The number 2 becomes the next digit in our result. 
Result so far: 4372.0
Subtract 1076 from 1283 to get 207.
Grab the next digit (0) from the dividend, add it to 207, then carry on: 2070 / 538

Going ahead to step 8:
538 goes into 2070 3 times with a remainder of 456.
Use 3 as the next digit of our solution. 
Result so far: 43723.0
If we subtract 1614 from 2070, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 9:
If we divide 4560 by 538, we get 8 and a remainder of 256.
The next digit of our result is 8. 
Result so far: 43723.8
The remainder is 256 after subtracting 4304 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
2560 divided by 538 is 4 with a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 43723.84
Deduct 2152 from 2560 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 11:
538 goes into 4080 7 times with a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 43723.847
Subtract 3766 from 4080 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 12:
538 goes into 3140 5 times with a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 43723.8475
Subtracting 2690 from 3140 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 13:
The number 538 fits into 4500 8 times, leaving a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 43723.84758
Deduct 4304 from 4500 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 14:
538 goes into 1960 3 times with a remainder of 346.
The number 3 becomes the next digit in our result. 
Result so far: 43723.847583
Deduct 1614 from 1960 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 15:
538 can be fit into 3460 6 times, resulting in a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 43723.8475836
If we subtract 3228 from 3460, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 16:
538 goes into 2320 4 times with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 43723.84758364
If we subtract 2152 from 2320, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 43723.84758364 with a remainder of 1.68e-07.
