12855836 divided by 150 
The aim is to understand the frequency of 150 in 12855836.

Going ahead to step 1:
1 divided by 150 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 150

Step 2:
The number 150 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 150

On to step 3:
When dividing 128 by 150, we get 0 with a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Grab the next digit (5) from the dividend, add it to 128, then carry on: 1285 / 150

Moving on to step 4:
150 goes into 1285 8 times with a remainder of 85.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 85 after subtracting 1200 from 1285.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 150

Going ahead to step 5:
When dividing 855 by 150, we get 5 with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 750 from 855, we get 105.
Fetch the next digit (8) from the dividend, attach it to 105 and continue: 1058 / 150

Going ahead to step 6:
The number 150 fits into 1058 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 857.0
The remainder is 8 after subtracting 1050 from 1058.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 150

On to step 7:
150 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 8570.0
Subtract 0 from 83 to get 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 150

Advancing to step 8:
When dividing 836 by 150, we get 5 with a remainder of 86.
The number 5 becomes the next digit in our result. 
Result so far: 85705.0
If we take 750 away from 836, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
The number 150 fits into 860 5 times, leaving a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 85705.5
If we subtract 750 from 860, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
If we divide 1100 by 150, we get 7 and a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 85705.57
The remainder is 50 after subtracting 1050 from 1100.
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:
When dividing 500 by 150, we get 3 with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 85705.573
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:
150 can be fit into 500 3 times, resulting in a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 85705.5733
Deduct 450 from 500 and we're left 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.

The final result is 85705.5733 with a remainder of 0.0005.
