651251 ÷ 26 
The aim is to understand the frequency of 26 in 651251.

Advancing to step 1:
26 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 26

Going ahead to step 2:
65 divided by 26 is 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 52 away from 65, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 26

On to step 3:
26 can be fit into 131 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 130 from 131 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 26

On to step 4:
The number 26 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 250.0
Subtract 0 from 12 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 26

Let's proceed to step 5:
When dividing 125 by 26, we get 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 2504.0
Subtract 104 from 125 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 26

Going ahead to step 6:
26 can be fit into 211 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 25048.0
Deduct 208 from 211 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 26 fits into 30 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 25048.1
If we subtract 26 from 30, we 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.

Advancing to step 8:
26 goes into 40 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 25048.11
If we subtract 26 from 40, we 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.

Our division results in 25048.11 with a remaining 0.014.
