We look at the division of 454789 by 26 
The aim is to understand the frequency of 26 in 454789.

Moving on to step 1:
4 divided by 26 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 26

On to step 2:
26 can be fit into 45 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 19 after subtracting 26 from 45.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 26

Step 3:
26 can be fit into 194 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 182 from 194 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 26

On to step 4:
26 can be fit into 127 4 times, resulting in a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 174.0
If we take 104 away from 127, we end up with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 26

On to step 5:
26 goes into 238 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 1749.0
If we take 234 away from 238, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 26

Advancing to step 6:
49 divided by 26 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 17491.0
Subtracting 26 from 49 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
26 can be fit into 230 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 17491.8
The remainder is 22 after subtracting 208 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
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: 17491.88
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.

The quotient of the division is 17491.88, and the remainder is 0.012.
