We look at the division of 724884 by 26 
The aim is to understand the frequency of 26 in 724884.

Going ahead to step 1:
When dividing 7 by 26, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 26

Going ahead to step 2:
When dividing 72 by 26, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 52 from 72 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 26

On to step 3:
When dividing 204 by 26, we get 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 22 after subtracting 182 from 204.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 26

Advancing to step 4:
26 goes into 228 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 278.0
The remainder is 20 after subtracting 208 from 228.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 26

Moving on to step 5:
26 can be fit into 208 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2788.0
The remainder is 0 after subtracting 208 from 208.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 26

Going ahead to step 6:
26 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 27880.0
If we take 0 away from 4, we end up 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.

Advancing to step 7:
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: 27880.1
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.

Step 8:
26 goes into 140 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 27880.15
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.

On to step 9:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 27880.153
Deduct 78 from 100 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.

Moving on to step 10:
220 divided by 26 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 27880.1538
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.

Advancing to step 11:
If we divide 120 by 26, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 27880.15384
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.

Moving on to step 12:
When dividing 160 by 26, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 27880.153846
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.

Moving on to step 13:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 27880.1538461
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.

Advancing to step 14:
26 goes into 140 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 27880.15384615
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 27880.15384615 with a remainder of 1e-08.
