We're dividing 35772127 by 28 
The aim is to understand the frequency of 28 in 35772127.

Let's proceed to step 1:
3 divided by 28 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 28

Step 2:
35 divided by 28 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 28 from 35 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 28

Moving on to step 3:
When dividing 77 by 28, we get 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 56 away from 77, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 28

Going ahead to step 4:
If we divide 217 by 28, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 127.0
The remainder is 21 after subtracting 196 from 217.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 28

Moving on to step 5:
The number 28 fits into 212 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 1277.0
Subtract 196 from 212 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 28

Advancing to step 6:
28 goes into 161 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 12775.0
Subtracting 140 from 161 leaves us with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 28

On to step 7:
If we divide 212 by 28, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 127757.0
Subtract 196 from 212 to get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 28

Advancing to step 8:
28 goes into 167 5 times with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 1277575.0
If we take 140 away from 167, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
28 can be fit into 270 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1277575.9
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 28 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1277575.96
Subtract 168 from 180 to get 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 11:
If we divide 120 by 28, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1277575.964
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.

Going ahead to step 12:
28 goes into 80 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1277575.9642
If we take 56 away from 80, we end up 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.

Moving on to step 13:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1277575.96428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 1277575.964285
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.

Let's proceed to step 15:
When dividing 200 by 28, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1277575.9642857
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.

Going ahead to step 16:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1277575.96428571
If we take 28 away from 40, we end up 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.

The final outcome is 1277575.96428571, with a leftover of 1.2e-08.
