987278 divided by 26 
The aim is to understand the frequency of 26 in 987278.

Let's proceed to step 1:
26 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 26

Let's proceed to step 2:
When dividing 98 by 26, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 78 from 98 and we're left with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 26

On to step 3:
When dividing 207 by 26, we get 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we subtract 182 from 207, we get 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 26

Advancing to step 4:
When dividing 252 by 26, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 379.0
If we subtract 234 from 252, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 26

Let's proceed to step 5:
When dividing 187 by 26, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 3797.0
Subtracting 182 from 187 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 26

On to step 6:
26 goes into 58 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 37972.0
Deduct 52 from 58 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.

Going ahead to step 7:
When dividing 60 by 26, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 37972.2
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.

Advancing to step 8:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 37972.23
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
26 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 37972.23
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.

Advancing to step 10:
200 divided by 26 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 37972.2307
If we subtract 182 from 200, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
26 goes into 180 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 37972.23076
If we subtract 156 from 180, we get 24.
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:
If we divide 240 by 26, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 37972.230769
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.

Moving on to step 13:
When dividing 60 by 26, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 37972.2307692
If we take 52 away from 60, 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 14:
80 divided by 26 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 37972.23076923
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.

Our division results in 37972.23076923 with a remaining 2e-09.
