We're dividing 45401874 by 136 
The aim is to understand the frequency of 136 in 45401874.

On to step 1:
When dividing 4 by 136, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 136

Going ahead to step 2:
The number 136 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 136

On to step 3:
454 divided by 136 is 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 408 from 454 and we're left with 46.
Fetch the next digit (0) from the dividend, attach it to 46 and continue: 460 / 136

Going ahead to step 4:
136 goes into 460 3 times with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 52 after subtracting 408 from 460.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 136

Moving on to step 5:
136 goes into 521 3 times with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 333.0
If we take 408 away from 521, we end up with 113.
Bring next digit (8) of the dividend behind the 113 and repeat the process: 1138 / 136

Going ahead to step 6:
136 goes into 1138 8 times with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 3338.0
Subtract 1088 from 1138 to get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 136

On to step 7:
When dividing 507 by 136, we get 3 with a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 33383.0
Deduct 408 from 507 and we're left with 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 136

Step 8:
994 divided by 136 is 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 333837.0
The remainder is 42 after subtracting 952 from 994.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
136 goes into 420 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 333837.3
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
120 divided by 136 is 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 333837.3
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
When dividing 1200 by 136, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 333837.308
Subtract 1088 from 1200 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
136 goes into 1120 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 333837.3088
Subtracting 1088 from 1120 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 333837.3088 with a remainder of 0.00032.
