We look at the division of 617210 by 26 
The aim is to understand the frequency of 26 in 617210.

Let's proceed 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.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 26

Advancing to step 2:
26 goes into 61 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 52 from 61 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 26

Moving on to step 3:
26 goes into 97 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 19 after subtracting 78 from 97.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 26

Moving on to step 4:
26 goes into 192 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 237.0
If we take 182 away from 192, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 26

On to step 5:
When dividing 101 by 26, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 2373.0
The remainder is 23 after subtracting 78 from 101.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 26

Advancing to step 6:
230 divided by 26 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 23738.0
Deduct 208 from 230 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.

Going ahead to step 7:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 23738.8
If we take 208 away from 220, we end up 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.

Step 8:
120 divided by 26 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 23738.84
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.

On to step 9:
The number 26 fits into 160 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 23738.846
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.

Step 10:
When dividing 40 by 26, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 23738.8461
Subtract 26 from 40 to get 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 11:
When dividing 140 by 26, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 23738.84615
Deduct 130 from 140 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
26 goes into 100 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 23738.846153
Subtract 78 from 100 to 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.

Going ahead to step 13:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 23738.8461538
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.

Moving on to step 14:
26 can be fit into 120 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 23738.84615384
If we take 104 away from 120, we end up 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.

The quotient of the division is 23738.84615384, and the remainder is 1.6e-08.
