We're dividing 26090361 by 528 
The aim is to understand the frequency of 528 in 26090361.

Going ahead to step 1:
528 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 528

Moving on to step 2:
528 goes into 26 0 times with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 528

On to step 3:
If we divide 260 by 528, we get 0 and a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 260 to get 260.
Include the next digit (9) from the dividend after 260, then repeat: 2609 / 528

Going ahead to step 4:
528 goes into 2609 4 times with a remainder of 497.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2112 from 2609, we get 497.
Append the next digit (0) from the dividend to 497 and continue with: 4970 / 528

Let's proceed to step 5:
4970 divided by 528 is 9 with a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 4752 away from 4970, we end up with 218.
Fetch the next digit (3) from the dividend, attach it to 218 and continue: 2183 / 528

Moving on to step 6:
528 can be fit into 2183 4 times, resulting in a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we subtract 2112 from 2183, we get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 528

Let's proceed to step 7:
If we divide 716 by 528, we get 1 and a remainder of 188.
The next digit of our result is 1. 
Result so far: 4941.0
Subtracting 528 from 716 leaves us with 188.
Grab the next digit (1) from the dividend, add it to 188, then carry on: 1881 / 528

Moving on to step 8:
The number 528 fits into 1881 3 times, leaving a remainder of 297.
The number 3 becomes the next digit in our result. 
Result so far: 49413.0
If we subtract 1584 from 1881, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
2970 divided by 528 is 5 with a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 49413.5
Subtracting 2640 from 2970 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
3300 divided by 528 is 6 with a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 49413.56
Subtract 3168 from 3300 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
1320 divided by 528 is 2 with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 49413.562
Subtract 1056 from 1320 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 12:
The number 528 fits into 2640 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49413.5625
Subtracting 2640 from 2640 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
If we divide 0 by 528, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49413.5625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
528 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49413.5625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 49413.5625 with a remainder of 0.0.
