We look at the division of 86573696 by 150 
The aim is to understand the frequency of 150 in 86573696.

Step 1:
150 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 150

Step 2:
150 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 150

Moving on to step 3:
If we divide 865 by 150, we get 5 and a remainder of 115.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 750 from 865 and we're left with 115.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 150

On to step 4:
When dividing 1157 by 150, we get 7 with a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 107 after subtracting 1050 from 1157.
Fetch the next digit (3) from the dividend, attach it to 107 and continue: 1073 / 150

Moving on to step 5:
150 can be fit into 1073 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 577.0
The remainder is 23 after subtracting 1050 from 1073.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 150

Moving on to step 6:
If we divide 236 by 150, we get 1 and a remainder of 86.
The next digit of our result is 1. 
Result so far: 5771.0
If we subtract 150 from 236, we get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 150

On to step 7:
150 can be fit into 869 5 times, resulting in a remainder of 119.
Use 5 as the next digit of our solution. 
Result so far: 57715.0
The remainder is 119 after subtracting 750 from 869.
Fetch the next digit (6) from the dividend, attach it to 119 and continue: 1196 / 150

Going ahead to step 8:
The number 150 fits into 1196 7 times, leaving a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 577157.0
Subtract 1050 from 1196 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
When dividing 1460 by 150, we get 9 with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 577157.9
If we take 1350 away from 1460, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
150 can be fit into 1100 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 577157.97
Subtracting 1050 from 1100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
150 can be fit into 500 3 times, resulting in a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 577157.973
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 150, we get 3 and a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 577157.9733
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 577157.9733 with a remainder of 0.0005.
