We divide 838160 by 28
The aim is to understand the frequency of 28 in 838160.

Step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 28

Going ahead to step 2:
83 divided by 28 is 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 83 to get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 28

Going ahead to step 3:
When dividing 278 by 28, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 252 from 278 and we're left with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 28

Advancing to step 4:
The number 28 fits into 261 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 299.0
Subtracting 252 from 261 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 28

Moving on to step 5:
96 divided by 28 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 2993.0
If we subtract 84 from 96, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 28

Moving on to step 6:
120 divided by 28 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 29934.0
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 29934.2
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 28, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 29934.28
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 29934.285
If we take 140 away from 160, we end up 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.

Going ahead to step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 29934.2857
Subtracting 196 from 200 leaves us 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.

Moving on to step 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 29934.28571
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.

Let's proceed to step 12:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 29934.285714
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.

Going ahead to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 29934.2857142
If we subtract 56 from 80, we get 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 14:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 29934.28571428
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.

Our division results in 29934.28571428 with a remaining 1.6e-08.
