356890 ÷ 26 
The aim is to understand the frequency of 26 in 356890.

Moving on to step 1:
3 divided by 26 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 26

Moving on to step 2:
35 divided by 26 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 26 from 35, we get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 26

Step 3:
26 can be fit into 96 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 78 from 96 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 26

Advancing to step 4:
26 goes into 188 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Deduct 182 from 188 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 26

Let's proceed to step 5:
69 divided by 26 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 1372.0
If we subtract 52 from 69, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 26

Step 6:
When dividing 170 by 26, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 13726.0
Subtract 156 from 170 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.

On to step 7:
26 goes into 140 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 13726.5
The remainder is 10 after subtracting 130 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
26 goes into 100 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13726.53
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
26 can be fit into 220 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 13726.538
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.

Going ahead to step 10:
If we divide 120 by 26, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 13726.5384
Subtracting 104 from 120 leaves us with 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 11:
When dividing 160 by 26, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 13726.53846
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.

Step 12:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 13726.538461
The remainder is 14 after subtracting 26 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
140 divided by 26 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 13726.5384615
Deduct 130 from 140 and we're left 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.

Advancing to step 14:
If we divide 100 by 26, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 13726.53846153
Subtracting 78 from 100 leaves us 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.

The quotient of the division is 13726.53846153, and the remainder is 2.2e-08.
