We look at the division of 291443 by 26 
The aim is to understand the frequency of 26 in 291443.

Step 1:
If we divide 2 by 26, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 26

On to step 2:
The number 26 fits into 29 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 26 from 29, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 26

Let's proceed to step 3:
26 goes into 31 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 5 after subtracting 26 from 31.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 26

Advancing to step 4:
The number 26 fits into 54 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 52 from 54, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 26

Going ahead to step 5:
26 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 1120.0
If we subtract 0 from 24, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 26

Step 6:
When dividing 243 by 26, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 11209.0
If we subtract 234 from 243, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
26 can be fit into 90 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 11209.3
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 26, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 11209.34
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
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: 11209.346
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 26, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11209.3461
If we take 26 away from 40, we end up 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.

Advancing to step 11:
The number 26 fits into 140 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11209.34615
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.

On to step 12:
The number 26 fits into 100 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 11209.346153
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.

Let's proceed to step 13:
26 can be fit into 220 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11209.3461538
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.

Moving on to step 14:
26 can be fit into 120 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 11209.34615384
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.

After the division, we end up with 11209.34615384 and a remainder of 1.6e-08.
