We look at the division of 886271 by 28 
The aim is to understand the frequency of 28 in 886271.

On to step 1:
28 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 28

Advancing to step 2:
88 divided by 28 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 84 from 88 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 28

Step 3:
When dividing 46 by 28, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 28 from 46 and we're left with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 28

Step 4:
182 divided by 28 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
The remainder is 14 after subtracting 168 from 182.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 28

Advancing to step 5:
When dividing 147 by 28, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 3165.0
Subtracting 140 from 147 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 28

Advancing to step 6:
28 can be fit into 71 2 times, resulting in a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 31652.0
Deduct 56 from 71 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
28 goes into 150 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 31652.5
If we take 140 away from 150, we end up 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.

On 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: 31652.53
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.

Advancing to step 9:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 31652.535
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.

Going ahead to step 10:
When dividing 200 by 28, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 31652.5357
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.

Let's proceed to step 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 31652.53571
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.

Advancing to step 12:
28 goes into 120 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 31652.535714
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.

Moving on to step 13:
28 goes into 80 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 31652.5357142
Subtracting 56 from 80 leaves us 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.

Moving on to step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 31652.53571428
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.

The quotient of the division is 31652.53571428, and the remainder is 1.6e-08.
