651925 divided by 28 
The aim is to understand the frequency of 28 in 651925.

Let's proceed to step 1:
28 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 28

Advancing to step 2:
28 can be fit into 65 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 56 away from 65, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 28

Advancing to step 3:
91 divided by 28 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 84 from 91 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 28

Moving on to step 4:
79 divided by 28 is 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 232.0
The remainder is 23 after subtracting 56 from 79.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 28

Advancing to step 5:
If we divide 232 by 28, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2328.0
If we subtract 224 from 232, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 28

Going ahead to step 6:
28 can be fit into 85 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 23283.0
If we take 84 away from 85, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 28, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 23283.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
28 goes into 100 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 23283.03
If we subtract 84 from 100, we 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.

Step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 23283.035
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.

Going ahead to step 10:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 23283.0357
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 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 23283.03571
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 12:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 23283.035714
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.

Let's proceed to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 23283.0357142
The remainder is 24 after subtracting 56 from 80.
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 14:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 23283.03571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 23283.03571428, and the remainder is 1.6e-08.
