We look at the division of 10530587 by 135 
The aim is to understand the frequency of 135 in 10530587.

Step 1:
135 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 135

Advancing to step 2:
If we divide 10 by 135, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 135

Moving on to step 3:
135 can be fit into 105 0 times, resulting in a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 105 leaves us with 105.
Append the next digit (3) from the dividend to 105 and continue with: 1053 / 135

Going ahead to step 4:
135 can be fit into 1053 7 times, resulting in a remainder of 108.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 945 from 1053 leaves us with 108.
Bring next digit (0) of the dividend behind the 108 and repeat the process: 1080 / 135

On to step 5:
135 can be fit into 1080 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 0 after subtracting 1080 from 1080.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 135

Step 6:
5 divided by 135 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtract 0 from 5 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 135

Advancing to step 7:
The number 135 fits into 58 0 times, leaving a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 7800.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 135

Going ahead to step 8:
135 goes into 587 4 times with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 78004.0
Deduct 540 from 587 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
135 goes into 470 3 times with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 78004.3
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
135 can be fit into 650 4 times, resulting in a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 78004.34
Subtracting 540 from 650 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 11:
If we divide 1100 by 135, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 78004.348
Subtract 1080 from 1100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
135 goes into 200 1 times with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 78004.3481
If we subtract 135 from 200, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
135 can be fit into 650 4 times, resulting in a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 78004.34814
If we subtract 540 from 650, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 14:
1100 divided by 135 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 78004.348148
The remainder is 20 after subtracting 1080 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
The number 135 fits into 200 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 78004.3481481
The remainder is 65 after subtracting 135 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 16:
The number 135 fits into 650 4 times, leaving a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 78004.34814814
The remainder is 110 after subtracting 540 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 78004.34814814 and a remainder of 1.1e-07.
