We look at the division of 28571336 by 528 
The aim is to understand the frequency of 528 in 28571336.

Step 1:
528 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 528

Step 2:
If we divide 28 by 528, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 528

Step 3:
If we divide 285 by 528, we get 0 and a remainder of 285.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 285 and we're left with 285.
Append the next digit (7) from the dividend to 285 and continue with: 2857 / 528

Advancing to step 4:
When dividing 2857 by 528, we get 5 with a remainder of 217.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 2640 from 2857 leaves us with 217.
Fetch the next digit (1) from the dividend, attach it to 217 and continue: 2171 / 528

Step 5:
When dividing 2171 by 528, we get 4 with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 2112 from 2171 to get 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 528

Going ahead to step 6:
The number 528 fits into 593 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 541.0
The remainder is 65 after subtracting 528 from 593.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 528

Step 7:
If we divide 653 by 528, we get 1 and a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 5411.0
Subtracting 528 from 653 leaves us with 125.
Bring next digit (6) of the dividend behind the 125 and repeat the process: 1256 / 528

Moving on to step 8:
528 can be fit into 1256 2 times, resulting in a remainder of 200.
The next digit of our result is 2. 
Result so far: 54112.0
Deduct 1056 from 1256 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 9:
If we divide 2000 by 528, we get 3 and a remainder of 416.
The number 3 becomes the next digit in our result. 
Result so far: 54112.3
The remainder is 416 after subtracting 1584 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 10:
528 goes into 4160 7 times with a remainder of 464.
Put 7 as the next digit of the answer. 
Result so far: 54112.37
Subtracting 3696 from 4160 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 11:
528 goes into 4640 8 times with a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 54112.378
Deduct 4224 from 4640 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 12:
528 goes into 4160 7 times with a remainder of 464.
Record the quotient 7 as the next digit in the result. 
Result so far: 54112.3787
Deduct 3696 from 4160 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
If we divide 4640 by 528, we get 8 and a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 54112.37878
Subtracting 4224 from 4640 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
If we divide 4160 by 528, we get 7 and a remainder of 464.
Write down 7 as next digit of the result. 
Result so far: 54112.378787
If we take 3696 away from 4160, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 15:
528 goes into 4640 8 times with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 54112.3787878
The remainder is 416 after subtracting 4224 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 16:
If we divide 4160 by 528, we get 7 and a remainder of 464.
Put 7 as the next digit of the answer. 
Result so far: 54112.37878787
The remainder is 464 after subtracting 3696 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 54112.37878787, with a leftover of 4.64e-07.
