Let's divide 30140925 by 528
The aim is to understand the frequency of 528 in 30140925.

Step 1:
If we divide 3 by 528, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 528

Step 2:
The number 528 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 528

Let's proceed to step 3:
301 divided by 528 is 0 with a remainder of 301.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 301 after subtracting 0 from 301.
Grab the next digit (4) from the dividend, add it to 301, then carry on: 3014 / 528

Let's proceed to step 4:
528 goes into 3014 5 times with a remainder of 374.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 2640 from 3014, we get 374.
Bring next digit (0) of the dividend behind the 374 and repeat the process: 3740 / 528

Step 5:
528 goes into 3740 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 44 after subtracting 3696 from 3740.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 528

Moving on to step 6:
528 can be fit into 449 0 times, resulting in a remainder of 449.
Use 0 as the next digit of our solution. 
Result so far: 570.0
Subtracting 0 from 449 leaves us with 449.
Bring next digit (2) of the dividend behind the 449 and repeat the process: 4492 / 528

Advancing to step 7:
If we divide 4492 by 528, we get 8 and a remainder of 268.
The next digit of our result is 8. 
Result so far: 5708.0
Subtract 4224 from 4492 to get 268.
Bring next digit (5) of the dividend behind the 268 and repeat the process: 2685 / 528

On to step 8:
The number 528 fits into 2685 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 57085.0
The remainder is 45 after subtracting 2640 from 2685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
The number 528 fits into 450 0 times, leaving a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 57085.0
Subtracting 0 from 450 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.

Advancing to step 10:
The number 528 fits into 4500 8 times, leaving a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 57085.08
If we subtract 4224 from 4500, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
2760 divided by 528 is 5 with a remainder of 120.
The next digit of our result is 5. 
Result so far: 57085.085
Subtract 2640 from 2760 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
528 goes into 1200 2 times with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 57085.0852
If we take 1056 away from 1200, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
The number 528 fits into 1440 2 times, leaving a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 57085.08522
If we take 1056 away from 1440, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 57085.08522 with a remainder of 0.000384.
