We're dividing 801950 by 28 
The aim is to understand the frequency of 28 in 801950.

Moving on to step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 28

On to step 2:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 80 to get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 28

On to step 3:
If we divide 241 by 28, we get 8 and a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 224 from 241 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 28

Moving on to step 4:
The number 28 fits into 179 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 286.0
The remainder is 11 after subtracting 168 from 179.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 28

Advancing to step 5:
28 can be fit into 115 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 2864.0
Deduct 112 from 115 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 28

Moving on to step 6:
If we divide 30 by 28, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 28641.0
Subtracting 28 from 30 leaves us 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.

On 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: 28641.0
Subtracting 0 from 20 leaves us 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 8:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 28641.07
If we subtract 196 from 200, we 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.

Moving on to step 9:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 28641.071
If we subtract 28 from 40, we 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 10:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 28641.0714
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.

Going ahead to step 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 28641.07142
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.

Moving on to step 12:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 28641.071428
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.

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: 28641.0714285
The remainder is 20 after subtracting 140 from 160.
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 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 28641.07142857
If we subtract 196 from 200, we 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.

The final outcome is 28641.07142857, with a leftover of 4e-09.
