861253 divided by 28 
The aim is to understand the frequency of 28 in 861253.

Step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 28

Going ahead to step 2:
When dividing 86 by 28, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 84 from 86 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 28

Let's proceed to step 3:
The number 28 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 28

Advancing to step 4:
If we divide 212 by 28, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 307.0
Deduct 196 from 212 and we're left with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 28

Let's proceed to step 5:
When dividing 165 by 28, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3075.0
If we take 140 away from 165, we end up with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 28

Step 6:
The number 28 fits into 253 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 30759.0
The remainder is 1 after subtracting 252 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 28 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 30759.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 28 fits into 100 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 30759.03
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:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 30759.035
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.

Let's proceed to step 10:
28 goes into 200 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 30759.0357
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 11:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 30759.03571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 30759.035714
If we subtract 112 from 120, we get 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 13:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 30759.0357142
Subtract 56 from 80 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.

Step 14:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 30759.03571428
If we subtract 224 from 240, 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.

The quotient of the division is 30759.03571428, and the remainder is 1.6e-08.
