79442218 ÷ 28 
The aim is to understand the frequency of 28 in 79442218.

Step 1:
If we divide 7 by 28, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 28

Let's proceed to step 2:
If we divide 79 by 28, we get 2 and a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 56 away from 79, we end up with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 28

Step 3:
28 goes into 234 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 224 from 234 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 28

On to step 4:
If we divide 104 by 28, we get 3 and a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 283.0
If we subtract 84 from 104, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 28

On to step 5:
The number 28 fits into 202 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 2837.0
Subtract 196 from 202 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 28

Going ahead to step 6:
62 divided by 28 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 28372.0
If we take 56 away from 62, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 28

Moving on to step 7:
The number 28 fits into 61 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 283722.0
Deduct 56 from 61 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 28

On to step 8:
If we divide 58 by 28, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2837222.0
Deduct 56 from 58 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
20 divided by 28 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2837222.0
The remainder is 20 after subtracting 0 from 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 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 2837222.07
Subtract 196 from 200 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.

Let's proceed to step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 2837222.071
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 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2837222.0714
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.

Moving on to step 13:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2837222.07142
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.

Advancing to step 14:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 2837222.071428
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.

On to step 15:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2837222.0714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 2837222.07142857
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.

The final result is 2837222.07142857 with a remainder of 4e-09.
