We're dividing 28518519 by 389 
The aim is to understand the frequency of 389 in 28518519.

Going ahead to step 1:
If we divide 2 by 389, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 389

Moving on to step 2:
When dividing 28 by 389, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 389

Step 3:
If we divide 285 by 389, we get 0 and a remainder of 285.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 285 and we're left with 285.
Include the next digit (1) from the dividend after 285, then repeat: 2851 / 389

Advancing to step 4:
389 goes into 2851 7 times with a remainder of 128.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2723 from 2851 to get 128.
Fetch the next digit (8) from the dividend, attach it to 128 and continue: 1288 / 389

Going ahead to step 5:
1288 divided by 389 is 3 with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 121 after subtracting 1167 from 1288.
Take the next digit (5) from the dividend and append it to 121, then repeat: 1215 / 389

Step 6:
When dividing 1215 by 389, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 733.0
If we take 1167 away from 1215, we end up with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 389

On to step 7:
389 can be fit into 481 1 times, resulting in a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 7331.0
If we subtract 389 from 481, we get 92.
Append the next digit (9) from the dividend to 92 and continue with: 929 / 389

Moving on to step 8:
The number 389 fits into 929 2 times, leaving a remainder of 151.
The next digit of our result is 2. 
Result so far: 73312.0
Subtract 778 from 929 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 9:
The number 389 fits into 1510 3 times, leaving a remainder of 343.
Write down 3 as next digit of the result. 
Result so far: 73312.3
Deduct 1167 from 1510 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 10:
When dividing 3430 by 389, we get 8 with a remainder of 318.
Write down 8 as next digit of the result. 
Result so far: 73312.38
If we subtract 3112 from 3430, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 11:
389 can be fit into 3180 8 times, resulting in a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 73312.388
Subtracting 3112 from 3180 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 73312.388 with a remaining 0.0068.
