We look at the division of 32394934 by 28 
The aim is to understand the frequency of 28 in 32394934.

On to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 28

Moving on to step 2:
28 goes into 32 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 28 from 32, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 28

Moving on to step 3:
28 goes into 43 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 15 after subtracting 28 from 43.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 28

Let's proceed to step 4:
28 can be fit into 159 5 times, resulting in a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we subtract 140 from 159, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 28

Step 5:
28 goes into 194 6 times with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 1156.0
The remainder is 26 after subtracting 168 from 194.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 28

Moving on to step 6:
When dividing 269 by 28, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 11569.0
Deduct 252 from 269 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 28

Let's proceed to step 7:
173 divided by 28 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 115696.0
If we take 168 away from 173, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 28

Step 8:
54 divided by 28 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1156961.0
Deduct 28 from 54 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 28 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 1156961.9
Deduct 252 from 260 and we're left with 8.
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 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 1156961.92
Subtracting 56 from 80 leaves us 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 11:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 1156961.928
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 12:
28 goes into 160 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1156961.9285
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.

Moving on to step 13:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 1156961.92857
If we take 196 away from 200, we end up 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.

Going ahead to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1156961.928571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 1156961.9285714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 16:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1156961.92857142
Subtracting 56 from 80 leaves us 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.

After the division, we end up with 1156961.92857142 and a remainder of 2.4e-08.
