43359521 divided by 136 
The aim is to understand the frequency of 136 in 43359521.

Step 1:
136 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 136

Let's proceed to step 2:
If we divide 43 by 136, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 136

Step 3:
433 divided by 136 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 25 after subtracting 408 from 433.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 136

Moving on to step 4:
255 divided by 136 is 1 with a remainder of 119.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 136 from 255 and we're left with 119.
Bring next digit (9) of the dividend behind the 119 and repeat the process: 1199 / 136

Let's proceed to step 5:
When dividing 1199 by 136, we get 8 with a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
Subtract 1088 from 1199 to get 111.
Take the next digit (5) from the dividend and append it to 111, then repeat: 1115 / 136

Going ahead to step 6:
136 goes into 1115 8 times with a remainder of 27.
The next digit of our result is 8. 
Result so far: 3188.0
Subtracting 1088 from 1115 leaves us with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 136

Advancing to step 7:
136 goes into 272 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 31882.0
Deduct 272 from 272 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 136

On to step 8:
136 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 318820.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
10 divided by 136 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 318820.0
The remainder is 10 after subtracting 0 from 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 10:
100 divided by 136 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 318820.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 318820.0 and a remainder of 0.1.
