Let's divide 71615891 by 136
The aim is to understand the frequency of 136 in 71615891.

On to step 1:
When dividing 7 by 136, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 136

Advancing to step 2:
71 divided by 136 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 136

Moving on to step 3:
The number 136 fits into 716 5 times, leaving a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 36 after subtracting 680 from 716.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 136

On to step 4:
361 divided by 136 is 2 with a remainder of 89.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 89 after subtracting 272 from 361.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 136

Moving on to step 5:
The number 136 fits into 895 6 times, leaving a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 526.0
Subtracting 816 from 895 leaves us with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 136

Let's proceed to step 6:
If we divide 798 by 136, we get 5 and a remainder of 118.
Use 5 as the next digit of our solution. 
Result so far: 5265.0
Subtract 680 from 798 to get 118.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 136

Step 7:
136 goes into 1189 8 times with a remainder of 101.
Write down 8 as next digit of the result. 
Result so far: 52658.0
Subtract 1088 from 1189 to get 101.
Grab the next digit (1) from the dividend, add it to 101, then carry on: 1011 / 136

Advancing to step 8:
136 goes into 1011 7 times with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 526587.0
Subtracting 952 from 1011 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
590 divided by 136 is 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 526587.4
Subtract 544 from 590 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
136 can be fit into 460 3 times, resulting in a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 526587.43
Deduct 408 from 460 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
When dividing 520 by 136, we get 3 with a remainder of 112.
The next digit of our result is 3. 
Result so far: 526587.433
If we take 408 away from 520, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 526587.433 and a remainder of 0.0112.
