Let's divide 728009 by 26
The aim is to understand the frequency of 26 in 728009.

On to step 1:
26 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 26

Let's proceed to step 2:
26 can be fit into 72 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 52 from 72, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 26

Moving on to step 3:
If we divide 208 by 26, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 0 after subtracting 208 from 208.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 26

Moving on to step 4:
26 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 26

Advancing to step 5:
The number 26 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2800.0
If we take 0 away from 0, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 26

Moving on to step 6:
The number 26 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 28000.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
26 goes into 90 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 28000.3
Subtracting 78 from 90 leaves us 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.

Moving on to step 8:
120 divided by 26 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 28000.34
The remainder is 16 after subtracting 104 from 120.
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 9:
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: 28000.346
If we subtract 156 from 160, 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.

On to step 10:
26 can be fit into 40 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 28000.3461
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.

Step 11:
140 divided by 26 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 28000.34615
If we subtract 130 from 140, we 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.

Advancing to step 12:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 28000.346153
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.

Moving on to step 13:
If we divide 220 by 26, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 28000.3461538
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.

Moving on to step 14:
When dividing 120 by 26, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 28000.34615384
If we take 104 away from 120, we end up 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.

The final outcome is 28000.34615384, with a leftover of 1.6e-08.
