We look at the division of 57872090 by 528 
The aim is to understand the frequency of 528 in 57872090.

Advancing to step 1:
If we divide 5 by 528, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 528

Step 2:
When dividing 57 by 528, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 528

Advancing to step 3:
528 can be fit into 578 1 times, resulting in a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 528 from 578 and we're left with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 528

Moving on to step 4:
507 divided by 528 is 0 with a remainder of 507.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 507 and we're left with 507.
Take the next digit (2) from the dividend and append it to 507, then repeat: 5072 / 528

Step 5:
5072 divided by 528 is 9 with a remainder of 320.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtracting 4752 from 5072 leaves us with 320.
Grab the next digit (0) from the dividend, add it to 320, then carry on: 3200 / 528

Let's proceed to step 6:
The number 528 fits into 3200 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 1096.0
The remainder is 32 after subtracting 3168 from 3200.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 528

Step 7:
528 can be fit into 329 0 times, resulting in a remainder of 329.
Write down 0 as next digit of the result. 
Result so far: 10960.0
Subtracting 0 from 329 leaves us with 329.
Fetch the next digit (0) from the dividend, attach it to 329 and continue: 3290 / 528

Step 8:
528 can be fit into 3290 6 times, resulting in a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 109606.0
The remainder is 122 after subtracting 3168 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
528 goes into 1220 2 times with a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 109606.2
If we subtract 1056 from 1220, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
When dividing 1640 by 528, we get 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 109606.23
Subtract 1584 from 1640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
528 goes into 560 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 109606.231
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
The number 528 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 109606.231
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
528 can be fit into 3200 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 109606.23106
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 528, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 109606.23106
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
3200 divided by 528 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 109606.2310606
If we take 3168 away from 3200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
The number 528 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 109606.2310606
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 109606.2310606 and a remainder of 3.2e-07.
