53380728 ÷ 150 
The aim is to understand the frequency of 150 in 53380728.

Let's proceed to step 1:
If we divide 5 by 150, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 150

Going ahead to step 2:
When dividing 53 by 150, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 150

Moving on to step 3:
When dividing 533 by 150, we get 3 with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 450 from 533 and we're left with 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 150

Moving on to step 4:
When dividing 838 by 150, we get 5 with a remainder of 88.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 750 away from 838, we end up with 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 150

Advancing to step 5:
880 divided by 150 is 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 355.0
The remainder is 130 after subtracting 750 from 880.
Fetch the next digit (7) from the dividend, attach it to 130 and continue: 1307 / 150

On to step 6:
If we divide 1307 by 150, we get 8 and a remainder of 107.
Record the quotient 8 as the next digit in the result. 
Result so far: 3558.0
The remainder is 107 after subtracting 1200 from 1307.
Include the next digit (2) from the dividend after 107, then repeat: 1072 / 150

Let's proceed to step 7:
1072 divided by 150 is 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 35587.0
Subtract 1050 from 1072 to get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 150

Moving on to step 8:
228 divided by 150 is 1 with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 355871.0
Deduct 150 from 228 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
When dividing 780 by 150, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 355871.5
Subtracting 750 from 780 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 150, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 355871.52
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
150 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 355871.52
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.

Advancing to step 12:
When dividing 0 by 150, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 355871.52
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.

After the division, we end up with 355871.52 and a remainder of 0.0.
