730111 ÷ 28 
The aim is to understand the frequency of 28 in 730111.

Moving on to step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 28

On to step 2:
If we divide 73 by 28, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 56 from 73 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 28

Advancing to step 3:
If we divide 170 by 28, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 168 away from 170, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 28

Moving on to step 4:
When dividing 21 by 28, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 260.0
Subtract 0 from 21 to get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 28

Going ahead to step 5:
28 goes into 211 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 2607.0
Subtract 196 from 211 to get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 28

Moving on to step 6:
151 divided by 28 is 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 26075.0
The remainder is 11 after subtracting 140 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 28, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 26075.3
Subtracting 84 from 110 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.

Step 8:
If we divide 260 by 28, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 26075.39
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.

Moving on to step 9:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 26075.392
If we subtract 56 from 80, we 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:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 26075.3928
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.

Moving on to step 11:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 26075.39285
If we take 140 away from 160, we end up 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.

Let's proceed to step 12:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 26075.392857
Subtract 196 from 200 to 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.

Advancing to step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 26075.3928571
Subtract 28 from 40 to 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.

Step 14:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 26075.39285714
Subtract 112 from 120 to 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.

The final outcome is 26075.39285714, with a leftover of 8e-09.
