We look at the division of 26390853 by 135 
The aim is to understand the frequency of 135 in 26390853.

Going ahead to step 1:
When dividing 2 by 135, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 135

On to step 2:
26 divided by 135 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 135

Moving on to step 3:
If we divide 263 by 135, we get 1 and a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 135 from 263, we get 128.
Grab the next digit (9) from the dividend, add it to 128, then carry on: 1289 / 135

On to step 4:
The number 135 fits into 1289 9 times, leaving a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 74 after subtracting 1215 from 1289.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 135

Step 5:
740 divided by 135 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtract 675 from 740 to get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 135

Let's proceed to step 6:
658 divided by 135 is 4 with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 1954.0
If we subtract 540 from 658, we get 118.
Append the next digit (5) from the dividend to 118 and continue with: 1185 / 135

Moving on to step 7:
When dividing 1185 by 135, we get 8 with a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 19548.0
If we take 1080 away from 1185, we end up with 105.
Fetch the next digit (3) from the dividend, attach it to 105 and continue: 1053 / 135

Let's proceed to step 8:
135 can be fit into 1053 7 times, resulting in a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 195487.0
Subtracting 945 from 1053 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
If we divide 1080 by 135, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 195487.8
If we subtract 1080 from 1080, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 135, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 195487.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 135, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 195487.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 195487.8, with a leftover of 0.0.
