405593 ÷ 26 
The aim is to understand the frequency of 26 in 405593.

Moving on to step 1:
The number 26 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 26

Let's proceed to step 2:
26 can be fit into 40 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 26 from 40 leaves us with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 26

Step 3:
26 goes into 145 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 130 from 145 to get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 26

Going ahead to step 4:
When dividing 155 by 26, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 25 after subtracting 130 from 155.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 26

Let's proceed to step 5:
259 divided by 26 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 1559.0
Subtracting 234 from 259 leaves us with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 26

On to step 6:
253 divided by 26 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 15599.0
The remainder is 19 after subtracting 234 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
If we divide 190 by 26, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 15599.7
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 26 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 15599.73
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 26 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 15599.73
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
When dividing 200 by 26, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 15599.7307
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
26 can be fit into 180 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 15599.73076
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 26 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 15599.730769
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
26 goes into 60 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15599.7307692
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
80 divided by 26 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 15599.73076923
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 15599.73076923 and a remainder of 2e-09.
