We're dividing 253031 by 26 
The aim is to understand the frequency of 26 in 253031.

Step 1:
The number 26 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 26

Moving on to step 2:
26 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 26

Step 3:
When dividing 253 by 26, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 234 from 253 to get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 26

Advancing to step 4:
26 can be fit into 190 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 8 after subtracting 182 from 190.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 26

On to step 5:
26 goes into 83 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 973.0
Deduct 78 from 83 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 26

Step 6:
26 can be fit into 51 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 9731.0
The remainder is 25 after subtracting 26 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
26 goes into 250 9 times with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 9731.9
Subtract 234 from 250 to 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.

On to step 8:
If we divide 160 by 26, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 9731.96
Deduct 156 from 160 and we're left 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 9:
26 can be fit into 40 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 9731.961
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.

Moving on to step 10:
140 divided by 26 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9731.9615
Subtracting 130 from 140 leaves us 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.

Advancing to step 11:
100 divided by 26 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 9731.96153
If we take 78 away from 100, we end up 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.

Advancing to step 12:
26 can be fit into 220 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 9731.961538
Subtracting 208 from 220 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.

Let's proceed to step 13:
The number 26 fits into 120 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 9731.9615384
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.

Advancing to step 14:
If we divide 160 by 26, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9731.96153846
Deduct 156 from 160 and we're left 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.

After the division, we end up with 9731.96153846 and a remainder of 4e-09.
