717116 ÷ 28 
The aim is to understand the frequency of 28 in 717116.

Advancing to step 1:
28 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 28

Going ahead to step 2:
If we divide 71 by 28, we get 2 and a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 56 from 71 and we're left with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 28

Moving on to step 3:
28 goes into 157 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 140 from 157 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 28

Let's proceed to step 4:
28 can be fit into 171 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 256.0
Deduct 168 from 171 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 28

On to step 5:
28 can be fit into 31 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 2561.0
Subtract 28 from 31 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 28

On to step 6:
28 can be fit into 36 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 25611.0
If we subtract 28 from 36, 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.

Moving on to step 7:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 25611.2
If we take 56 away from 80, we end up 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.

Advancing to step 8:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25611.28
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.

Advancing to step 9:
28 goes into 160 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 25611.285
Deduct 140 from 160 and we're left 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 10:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 25611.2857
The remainder is 4 after subtracting 196 from 200.
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 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 25611.28571
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:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 25611.285714
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:
When dividing 80 by 28, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 25611.2857142
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.

Let's proceed to step 14:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 25611.28571428
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.

Our division results in 25611.28571428 with a remaining 1.6e-08.
