We look at the division of 846731 by 28 
The aim is to understand the frequency of 28 in 846731.

Let's proceed to step 1:
If we divide 8 by 28, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 28

Advancing to step 2:
If we divide 84 by 28, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 84 from 84 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 28

Step 3:
28 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 28

Step 4:
28 goes into 67 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 302.0
If we subtract 56 from 67, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 28

Going ahead to step 5:
28 goes into 113 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 3024.0
Subtracting 112 from 113 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 28

Let's proceed to step 6:
When dividing 11 by 28, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 30240.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 28 fits into 110 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 30240.3
Subtracting 84 from 110 leaves us 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.

On to step 8:
260 divided by 28 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 30240.39
Subtracting 252 from 260 leaves us 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 9:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 30240.392
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.

Going ahead to step 10:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 30240.3928
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.

On to step 11:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 30240.39285
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.

Going ahead to step 12:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 30240.392857
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 13:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 30240.3928571
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.

On to step 14:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 30240.39285714
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.

The final outcome is 30240.39285714, with a leftover of 8e-09.
