We're dividing 87280724 by 385 
The aim is to understand the frequency of 385 in 87280724.

On to step 1:
The number 385 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 385

On to step 2:
385 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 385

Let's proceed to step 3:
If we divide 872 by 385, we get 2 and a remainder of 102.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 102 after subtracting 770 from 872.
Take the next digit (8) from the dividend and append it to 102, then repeat: 1028 / 385

Let's proceed to step 4:
385 can be fit into 1028 2 times, resulting in a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 770 from 1028 leaves us with 258.
Take the next digit (0) from the dividend and append it to 258, then repeat: 2580 / 385

Going ahead to step 5:
385 can be fit into 2580 6 times, resulting in a remainder of 270.
The next digit of our result is 6. 
Result so far: 226.0
Subtract 2310 from 2580 to get 270.
Append the next digit (7) from the dividend to 270 and continue with: 2707 / 385

Moving on to step 6:
The number 385 fits into 2707 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 2267.0
If we subtract 2695 from 2707, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 385

Step 7:
385 goes into 122 0 times with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 22670.0
Deduct 0 from 122 and we're left with 122.
Append the next digit (4) from the dividend to 122 and continue with: 1224 / 385

On to step 8:
385 can be fit into 1224 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 226703.0
If we subtract 1155 from 1224, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
385 can be fit into 690 1 times, resulting in a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 226703.1
Subtract 385 from 690 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 10:
When dividing 3050 by 385, we get 7 with a remainder of 355.
The number 7 becomes the next digit in our result. 
Result so far: 226703.17
Subtracting 2695 from 3050 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 11:
If we divide 3550 by 385, we get 9 and a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 226703.179
If we take 3465 away from 3550, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
850 divided by 385 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 226703.1792
If we subtract 770 from 850, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
When dividing 800 by 385, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 226703.17922
Subtract 770 from 800 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.

Our division results in 226703.17922 with a remaining 3e-05.
