770781 ÷ 28 
The aim is to understand the frequency of 28 in 770781.

Advancing to step 1:
28 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 28

Step 2:
28 goes into 77 2 times with a remainder of 21.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 56 from 77 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 28

Let's proceed to step 3:
210 divided by 28 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 14 after subtracting 196 from 210.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 28

Let's proceed to step 4:
28 can be fit into 147 5 times, resulting in a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 275.0
Subtracting 140 from 147 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 28

On to step 5:
The number 28 fits into 78 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2752.0
If we take 56 away from 78, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 28

Going ahead to step 6:
221 divided by 28 is 7 with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 27527.0
If we take 196 away from 221, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
28 goes into 250 8 times with a remainder of 26.
The next digit of our result is 8. 
Result so far: 27527.8
Subtracting 224 from 250 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.

Advancing to step 8:
The number 28 fits into 260 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 27527.89
The remainder is 8 after subtracting 252 from 260.
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:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 27527.892
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.

Advancing to step 10:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 27527.8928
Subtract 224 from 240 to 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 11:
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: 27527.89285
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.

On to step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 27527.892857
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.

Going ahead to step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 27527.8928571
If we take 28 away from 40, we end up 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.

Let's proceed to step 14:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 27527.89285714
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.

The final outcome is 27527.89285714, with a leftover of 8e-09.
