We're dividing 20990008 by 135 
The aim is to understand the frequency of 135 in 20990008.

Let's proceed to step 1:
135 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 135

Going ahead to step 2:
135 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 135

Moving on to step 3:
If we divide 209 by 135, we get 1 and a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 135 from 209, we get 74.
Grab the next digit (9) from the dividend, add it to 74, then carry on: 749 / 135

Step 4:
When dividing 749 by 135, we get 5 with a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 675 from 749, we get 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 135

Step 5:
135 can be fit into 740 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we take 675 away from 740, we end up with 65.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 135

Step 6:
If we divide 650 by 135, we get 4 and a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 1554.0
Subtract 540 from 650 to get 110.
Include the next digit (0) from the dividend after 110, then repeat: 1100 / 135

Going ahead to step 7:
135 goes into 1100 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 15548.0
Subtracting 1080 from 1100 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 135

Let's proceed to step 8:
135 goes into 208 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 155481.0
Subtract 135 from 208 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
730 divided by 135 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 155481.5
Subtract 675 from 730 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
135 goes into 550 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 155481.54
Deduct 540 from 550 and we're left 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:
135 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 155481.54
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
The number 135 fits into 1000 7 times, leaving a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 155481.5407
If we subtract 945 from 1000, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 13:
The number 135 fits into 550 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 155481.54074
Subtracting 540 from 550 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.

On to step 14:
If we divide 100 by 135, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 155481.54074
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
135 goes into 1000 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 155481.5407407
If we subtract 945 from 1000, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 16:
135 can be fit into 550 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 155481.54074074
Deduct 540 from 550 and we're left 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.

Our division results in 155481.54074074 with a remaining 1e-08.
