We divide 861885 by 28
The aim is to understand the frequency of 28 in 861885.

Advancing to step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 28

Going ahead to step 2:
28 can be fit into 86 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 84 away from 86, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 28

Going ahead to step 3:
The number 28 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 28

Moving on to step 4:
The number 28 fits into 218 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 307.0
The remainder is 22 after subtracting 196 from 218.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 28

Let's proceed to step 5:
228 divided by 28 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3078.0
Subtract 224 from 228 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 28

On to step 6:
45 divided by 28 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 30781.0
If we take 28 away from 45, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
If we divide 170 by 28, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 30781.6
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 28, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 30781.6
If we take 0 away from 20, 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 9:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 30781.607
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.

Step 10:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 30781.6071
Deduct 28 from 40 and we're left 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 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 30781.60714
If we take 112 away from 120, we end up 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.

Going ahead to step 12:
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: 30781.607142
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.

Advancing to step 13:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 30781.6071428
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.

Moving on to step 14:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 30781.60714285
Subtracting 140 from 160 leaves us 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.

After the division, we end up with 30781.60714285 and a remainder of 2e-08.
