We look at the division of 28857027 by 867 
The aim is to understand the frequency of 867 in 28857027.

On to step 1:
867 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 867

Going ahead to step 2:
867 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 867

Moving on to step 3:
867 can be fit into 288 0 times, resulting in a remainder of 288.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 288 after subtracting 0 from 288.
Append the next digit (5) from the dividend to 288 and continue with: 2885 / 867

Moving on to step 4:
867 goes into 2885 3 times with a remainder of 284.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2601 from 2885 and we're left with 284.
Include the next digit (7) from the dividend after 284, then repeat: 2847 / 867

Moving on to step 5:
The number 867 fits into 2847 3 times, leaving a remainder of 246.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Deduct 2601 from 2847 and we're left with 246.
Include the next digit (0) from the dividend after 246, then repeat: 2460 / 867

Moving on to step 6:
When dividing 2460 by 867, we get 2 with a remainder of 726.
The next digit of our result is 2. 
Result so far: 332.0
If we subtract 1734 from 2460, we get 726.
Append the next digit (2) from the dividend to 726 and continue with: 7262 / 867

Let's proceed to step 7:
If we divide 7262 by 867, we get 8 and a remainder of 326.
The next digit of our result is 8. 
Result so far: 3328.0
If we take 6936 away from 7262, we end up with 326.
Fetch the next digit (7) from the dividend, attach it to 326 and continue: 3267 / 867

Going ahead to step 8:
If we divide 3267 by 867, we get 3 and a remainder of 666.
Put 3 as the next digit of the answer. 
Result so far: 33283.0
Subtract 2601 from 3267 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 9:
If we divide 6660 by 867, we get 7 and a remainder of 591.
Record the quotient 7 as the next digit in the result. 
Result so far: 33283.7
The remainder is 591 after subtracting 6069 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Let's proceed to step 10:
If we divide 5910 by 867, we get 6 and a remainder of 708.
Record the quotient 6 as the next digit in the result. 
Result so far: 33283.76
Deduct 5202 from 5910 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 11:
If we divide 7080 by 867, we get 8 and a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 33283.768
Subtract 6936 from 7080 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
1440 divided by 867 is 1 with a remainder of 573.
The next digit of our result is 1. 
Result so far: 33283.7681
If we take 867 away from 1440, we end up with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 13:
If we divide 5730 by 867, we get 6 and a remainder of 528.
Use 6 as the next digit of our solution. 
Result so far: 33283.76816
If we subtract 5202 from 5730, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 14:
When dividing 5280 by 867, we get 6 with a remainder of 78.
The next digit of our result is 6. 
Result so far: 33283.768166
Subtracting 5202 from 5280 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 33283.768166 and a remainder of 7.8e-06.
