278459 ÷ 26 
The aim is to understand the frequency of 26 in 278459.

Step 1:
26 can be fit into 2 0 times, resulting in 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.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 26

Moving on to step 2:
When dividing 27 by 26, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 26 from 27, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 26

Advancing to step 3:
26 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 18, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 26

Step 4:
When dividing 184 by 26, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 107.0
Subtracting 182 from 184 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 26

Step 5:
26 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 1070.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 26

Moving on to step 6:
The number 26 fits into 259 9 times, leaving a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 10709.0
Subtract 234 from 259 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 26, we get 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 10709.9
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 26, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 10709.96
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
26 can be fit into 40 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 10709.961
Subtract 26 from 40 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
The number 26 fits into 140 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10709.9615
If we take 130 away from 140, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 10709.96153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 26, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 10709.961538
The remainder is 12 after subtracting 208 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
26 goes into 120 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 10709.9615384
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.

Advancing to step 14:
26 can be fit into 160 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 10709.96153846
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 10709.96153846, and the remainder is 4e-09.
