We look at the division of 10850901 by 150 
The aim is to understand the frequency of 150 in 10850901.

Moving 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
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 150

Advancing to step 2:
If we divide 10 by 150, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 150

Step 3:
If we divide 108 by 150, we get 0 and a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 108 leaves us with 108.
Bring next digit (5) of the dividend behind the 108 and repeat the process: 1085 / 150

Let's proceed to step 4:
1085 divided by 150 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 1050 from 1085 to get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 150

Step 5:
If we divide 350 by 150, we get 2 and a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtract 300 from 350 to get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 150

Let's proceed to step 6:
150 can be fit into 509 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 723.0
Subtracting 450 from 509 leaves us with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 150

On to step 7:
The number 150 fits into 590 3 times, leaving a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 7233.0
The remainder is 140 after subtracting 450 from 590.
Take the next digit (1) from the dividend and append it to 140, then repeat: 1401 / 150

On to step 8:
If we divide 1401 by 150, we get 9 and a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 72339.0
The remainder is 51 after subtracting 1350 from 1401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
150 goes into 510 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 72339.3
If we take 450 away from 510, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 150, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 72339.34
The remainder is 0 after subtracting 600 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 150 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 72339.34
Subtract 0 from 0 to get 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 12:
The number 150 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72339.34
If we subtract 0 from 0, we get 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 72339.34 with a remaining 0.0.
