We're dividing 87154184 by 158 
The aim is to understand the frequency of 158 in 87154184.

Moving on to step 1:
8 divided by 158 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 158

Going ahead to step 2:
87 divided by 158 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 158

Step 3:
The number 158 fits into 871 5 times, leaving a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 790 from 871, we get 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 158

Going ahead to step 4:
158 can be fit into 815 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 790 from 815 leaves us with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 158

Step 5:
158 goes into 254 1 times with a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 551.0
The remainder is 96 after subtracting 158 from 254.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 158

Let's proceed to step 6:
The number 158 fits into 961 6 times, leaving a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 5516.0
If we take 948 away from 961, we end up with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 158

Advancing to step 7:
The number 158 fits into 138 0 times, leaving a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 55160.0
If we subtract 0 from 138, we get 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 158

Advancing to step 8:
The number 158 fits into 1384 8 times, leaving a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 551608.0
If we subtract 1264 from 1384, we get 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 9:
If we divide 1200 by 158, we get 7 and a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 551608.7
Subtracting 1106 from 1200 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
158 can be fit into 940 5 times, resulting in a remainder of 150.
The next digit of our result is 5. 
Result so far: 551608.75
If we subtract 790 from 940, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
When dividing 1500 by 158, we get 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 551608.759
Subtracting 1422 from 1500 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
158 can be fit into 780 4 times, resulting in a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 551608.7594
If we subtract 632 from 780, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 13:
158 can be fit into 1480 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 551608.75949
Subtracting 1422 from 1480 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
580 divided by 158 is 3 with a remainder of 106.
The next digit of our result is 3. 
Result so far: 551608.759493
If we subtract 474 from 580, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 15:
The number 158 fits into 1060 6 times, leaving a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 551608.7594936
If we subtract 948 from 1060, we 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.

Moving on to step 16:
158 can be fit into 1120 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 551608.75949367
Deduct 1106 from 1120 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 551608.75949367 with a remainder of 1.4e-08.
