26289571 divided by 215 
The aim is to understand the frequency of 215 in 26289571.

Moving on to step 1:
215 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 215

Advancing to step 2:
If we divide 26 by 215, we get 0 and a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 215

Step 3:
215 can be fit into 262 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 47 after subtracting 215 from 262.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 215

Step 4:
215 can be fit into 478 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 430 from 478 to get 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 215

On to step 5:
When dividing 489 by 215, we get 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 430 from 489 to get 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 215

On to step 6:
The number 215 fits into 595 2 times, leaving a remainder of 165.
Use 2 as the next digit of our solution. 
Result so far: 1222.0
If we take 430 away from 595, we end up with 165.
Fetch the next digit (7) from the dividend, attach it to 165 and continue: 1657 / 215

Step 7:
If we divide 1657 by 215, we get 7 and a remainder of 152.
Put 7 as the next digit of the answer. 
Result so far: 12227.0
Deduct 1505 from 1657 and we're left with 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 215

Step 8:
If we divide 1521 by 215, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 122277.0
Deduct 1505 from 1521 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 215 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 122277.0
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
The number 215 fits into 1600 7 times, leaving a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 122277.07
Subtracting 1505 from 1600 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 11:
215 goes into 950 4 times with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 122277.074
If we subtract 860 from 950, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
215 goes into 900 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 122277.0744
Subtract 860 from 900 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 122277.0744 with a balance of 0.0004.
