We're dividing 1395200 by 150 
The aim is to understand the frequency of 150 in 1395200.

Let's proceed to step 1:
When dividing 1 by 150, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 150

Moving on to step 2:
13 divided by 150 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 150

Going ahead to step 3:
150 can be fit into 139 0 times, resulting in a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 139 and we're left with 139.
Grab the next digit (5) from the dividend, add it to 139, then carry on: 1395 / 150

Advancing to step 4:
When dividing 1395 by 150, we get 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 1350 away from 1395, we end up with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 150

Step 5:
The number 150 fits into 452 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 93.0
If we subtract 450 from 452, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 150

Step 6:
150 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 930.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 150

Step 7:
200 divided by 150 is 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 9301.0
If we subtract 150 from 200, we 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.

Going ahead to step 8:
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: 9301.3
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.

Step 9:
The number 150 fits into 500 3 times, leaving a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 9301.33
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.

The quotient of the division is 9301.33, and the remainder is 0.05.
