We look at the division of 43294209 by 136 
The aim is to understand the frequency of 136 in 43294209.

On to step 1:
4 divided by 136 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 136

Let's proceed to step 2:
The number 136 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 136

Let's proceed to step 3:
The number 136 fits into 432 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 408 from 432 leaves us with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 136

Going ahead to step 4:
When dividing 249 by 136, we get 1 with a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 113 after subtracting 136 from 249.
Take the next digit (4) from the dividend and append it to 113, then repeat: 1134 / 136

Advancing to step 5:
If we divide 1134 by 136, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 318.0
Subtracting 1088 from 1134 leaves us with 46.
Append the next digit (2) from the dividend to 46 and continue with: 462 / 136

On to step 6:
462 divided by 136 is 3 with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3183.0
Subtracting 408 from 462 leaves us with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 136

On to step 7:
136 goes into 540 3 times with a remainder of 132.
The number 3 becomes the next digit in our result. 
Result so far: 31833.0
Subtracting 408 from 540 leaves us with 132.
Bring next digit (9) of the dividend behind the 132 and repeat the process: 1329 / 136

Going ahead to step 8:
When dividing 1329 by 136, we get 9 with a remainder of 105.
The next digit of our result is 9. 
Result so far: 318339.0
Deduct 1224 from 1329 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
If we divide 1050 by 136, we get 7 and a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 318339.7
If we subtract 952 from 1050, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
When dividing 980 by 136, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 318339.77
If we take 952 away from 980, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 318339.77 with a remaining 0.028.
