1238040 ÷ 150 
The aim is to understand the frequency of 150 in 1238040.

On to step 1:
150 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 150

Moving on to step 2:
The number 150 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 150

On to step 3:
When dividing 123 by 150, we get 0 with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Bring next digit (8) of the dividend behind the 123 and repeat the process: 1238 / 150

Step 4:
150 goes into 1238 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 1200 from 1238, we get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 150

On to step 5:
150 can be fit into 380 2 times, resulting in a remainder of 80.
The next digit of our result is 2. 
Result so far: 82.0
The remainder is 80 after subtracting 300 from 380.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 150

Step 6:
150 goes into 804 5 times with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
Subtracting 750 from 804 leaves us with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 150

Let's proceed to step 7:
When dividing 540 by 150, we get 3 with a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 8253.0
Subtract 450 from 540 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 8:
150 can be fit into 900 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 8253.6
The remainder is 0 after subtracting 900 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
150 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8253.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 150, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8253.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8253.6 with a remaining 0.0.
