We divide 8955 by 28
The aim is to understand the frequency of 28 in 8955.

On to step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 28

Step 2:
If we divide 89 by 28, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 84 from 89 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 28

Moving on to step 3:
28 can be fit into 55 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 28 from 55 and we're left with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 28

Advancing to step 4:
The number 28 fits into 275 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 319.0
If we subtract 252 from 275, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 5:
28 can be fit into 230 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 319.8
Subtracting 224 from 230 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 6:
If we divide 60 by 28, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 319.82
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 319.821
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 319.8214
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 319.82142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 319.821428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 319.8214285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 319.82142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 319.82142857, with a leftover of 4e-09.
