19500801 ÷ 28 
The aim is to understand the frequency of 28 in 19500801.

On to step 1:
28 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 28

Let's proceed to step 2:
28 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 28

On to step 3:
195 divided by 28 is 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 168 from 195 to get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 28

Going ahead to step 4:
If we divide 270 by 28, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 252 from 270 and we're left with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 28

Going ahead to step 5:
When dividing 180 by 28, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 696.0
Deduct 168 from 180 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 28

On to step 6:
The number 28 fits into 128 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 6964.0
If we take 112 away from 128, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 28

Let's proceed to step 7:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 69645.0
Subtracting 140 from 160 leaves us with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 28

Step 8:
28 can be fit into 201 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 696457.0
If we subtract 196 from 201, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 28, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 696457.1
If we take 28 away from 50, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
220 divided by 28 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 696457.17
Subtract 196 from 220 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 696457.178
Deduct 224 from 240 and we're left 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 12:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 696457.1785
Subtract 140 from 160 to 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.

Step 13:
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: 696457.17857
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.

Advancing to step 14:
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: 696457.178571
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.

Going ahead to step 15:
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: 696457.1785714
Subtracting 112 from 120 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.

On to step 16:
If we divide 80 by 28, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 696457.17857142
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.

Our division results in 696457.17857142 with a remaining 2.4e-08.
