We look at the division of 65209938 by 150 
The aim is to understand the frequency of 150 in 65209938.

On to step 1:
150 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 150

Moving on to step 2:
The number 150 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 150

Going ahead to step 3:
150 goes into 652 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 600 from 652, we get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 150

Let's proceed to step 4:
If we divide 520 by 150, we get 3 and a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 70 after subtracting 450 from 520.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 150

On to step 5:
709 divided by 150 is 4 with a remainder of 109.
The next digit of our result is 4. 
Result so far: 434.0
If we take 600 away from 709, we end up with 109.
Take the next digit (9) from the dividend and append it to 109, then repeat: 1099 / 150

On to step 6:
1099 divided by 150 is 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 4347.0
Subtract 1050 from 1099 to get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 150

On to step 7:
493 divided by 150 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 43473.0
Subtract 450 from 493 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 150

Going ahead to step 8:
438 divided by 150 is 2 with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 434732.0
Deduct 300 from 438 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
The number 150 fits into 1380 9 times, leaving a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 434732.9
Subtract 1350 from 1380 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 150 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 434732.92
Subtracting 300 from 300 leaves us 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.

Advancing to step 11:
If we divide 0 by 150, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 434732.92
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.

Going ahead to step 12:
150 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 434732.92
Deduct 0 from 0 and we're left 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.

The final outcome is 434732.92, with a leftover of 0.0.
