We look at the division of 65989 by 26 
The aim is to understand the frequency of 26 in 65989.

Advancing to step 1:
When dividing 6 by 26, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 26

Let's proceed to step 2:
When dividing 65 by 26, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 52 from 65 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 26

Advancing to step 3:
26 can be fit into 139 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 130 from 139 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 26

On to step 4:
When dividing 98 by 26, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 253.0
If we subtract 78 from 98, we get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 26

Going ahead to step 5:
The number 26 fits into 209 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 2538.0
If we take 208 away from 209, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
The number 26 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2538.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 26, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 2538.03
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
When dividing 220 by 26, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2538.038
Deduct 208 from 220 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 26 fits into 120 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 2538.0384
Deduct 104 from 120 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 10:
26 goes into 160 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2538.03846
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
26 goes into 40 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 2538.038461
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
If we divide 140 by 26, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2538.0384615
The remainder is 10 after subtracting 130 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
26 goes into 100 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 2538.03846153
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 2538.03846153, and the remainder is 2.2e-08.
