We look at the division of 680846 by 26 
The aim is to understand the frequency of 26 in 680846.

Step 1:
26 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 26

Let's proceed to step 2:
The number 26 fits into 68 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 16 after subtracting 52 from 68.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 26

Advancing to step 3:
The number 26 fits into 160 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 156 from 160, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 26

On to step 4:
When dividing 48 by 26, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 261.0
Subtracting 26 from 48 leaves us with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 26

Going ahead to step 5:
The number 26 fits into 224 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2618.0
If we take 208 away from 224, we end up with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 26

Moving on to step 6:
26 goes into 166 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 26186.0
Deduct 156 from 166 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.

Step 7:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 26186.3
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 26, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 26186.38
If we subtract 208 from 220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
26 goes into 120 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 26186.384
Deduct 104 from 120 and we're left 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.

Going ahead to step 10:
If we divide 160 by 26, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 26186.3846
The remainder is 4 after subtracting 156 from 160.
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 11:
When dividing 40 by 26, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 26186.38461
Subtracting 26 from 40 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
26 goes into 140 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 26186.384615
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.

Advancing to step 13:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 26186.3846153
If we subtract 78 from 100, we 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.

Let's proceed to step 14:
26 goes into 220 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 26186.38461538
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 26186.38461538 and a remainder of 1.2e-08.
