613857 divided by 26 
The aim is to understand the frequency of 26 in 613857.

Let's proceed to step 1:
If we divide 6 by 26, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 26

Step 2:
The number 26 fits into 61 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 9 after subtracting 52 from 61.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 26

Going ahead to step 3:
93 divided by 26 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 15 after subtracting 78 from 93.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 26

Advancing to step 4:
26 goes into 158 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
The remainder is 2 after subtracting 156 from 158.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 26

Let's proceed to step 5:
25 divided by 26 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 2360.0
If we subtract 0 from 25, we get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 26

Advancing to step 6:
When dividing 257 by 26, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 23609.0
If we subtract 234 from 257, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
230 divided by 26 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 23609.8
Deduct 208 from 230 and we're left 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.

Going ahead to step 8:
When dividing 220 by 26, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 23609.88
Deduct 208 from 220 and we're left 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.

The quotient of the division is 23609.88, and the remainder is 0.012.
