We're dividing 361642 by 26 
The aim is to understand the frequency of 26 in 361642.

On to step 1:
If we divide 3 by 26, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 26

Step 2:
The number 26 fits into 36 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 26 from 36 and we're left with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 26

Step 3:
If we divide 101 by 26, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 78 from 101 to get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 26

Going ahead to step 4:
236 divided by 26 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtract 234 from 236 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 26

Moving on to step 5:
26 can be fit into 24 0 times, resulting in a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 1390.0
If we subtract 0 from 24, we get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 26

Going ahead to step 6:
242 divided by 26 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 13909.0
Deduct 234 from 242 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.

Let's proceed to step 7:
26 can be fit into 80 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 13909.3
If we subtract 78 from 80, we get 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 8:
The number 26 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 13909.3
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
26 can be fit into 200 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 13909.307
Subtracting 182 from 200 leaves us 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.

Advancing to step 10:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 13909.3076
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 13909.30769
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
If we divide 60 by 26, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 13909.307692
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
80 divided by 26 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13909.3076923
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.

Step 14:
When dividing 20 by 26, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13909.3076923
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 13909.3076923 with a remaining 2e-08.
