We're dividing 966422 by 28 
The aim is to understand the frequency of 28 in 966422.

Advancing to step 1:
When dividing 9 by 28, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 28

Advancing to step 2:
28 goes into 96 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 84 from 96 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 28

Let's proceed to step 3:
126 divided by 28 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 112 from 126, we get 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 28

Step 4:
When dividing 144 by 28, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
Deduct 140 from 144 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 28

Step 5:
If we divide 42 by 28, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 3451.0
Subtracting 28 from 42 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 28

Advancing to step 6:
When dividing 142 by 28, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 34515.0
Deduct 140 from 142 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.

Let's proceed to step 7:
When dividing 20 by 28, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 34515.0
Deduct 0 from 20 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.

On to step 8:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 34515.07
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.

Going ahead to step 9:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 34515.071
Deduct 28 from 40 and we're left 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 10:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 34515.0714
If we take 112 away from 120, we end up 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.

Let's proceed to step 11:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 34515.07142
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.

Advancing to step 12:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 34515.071428
Subtracting 224 from 240 leaves us 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.

Moving on to step 13:
28 goes into 160 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 34515.0714285
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.

Step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 34515.07142857
The remainder is 4 after subtracting 196 from 200.
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 34515.07142857, with a leftover of 4e-09.
