We look at the division of 28867578 by 326 
The aim is to understand the frequency of 326 in 28867578.

Going ahead to step 1:
When dividing 2 by 326, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 326

Step 2:
326 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 326

Moving on to step 3:
326 goes into 288 0 times with a remainder of 288.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Grab the next digit (6) from the dividend, add it to 288, then carry on: 2886 / 326

Going ahead to step 4:
When dividing 2886 by 326, we get 8 with a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 2608 from 2886, we get 278.
Take the next digit (7) from the dividend and append it to 278, then repeat: 2787 / 326

Step 5:
When dividing 2787 by 326, we get 8 with a remainder of 179.
The next digit of our result is 8. 
Result so far: 88.0
Subtracting 2608 from 2787 leaves us with 179.
Fetch the next digit (5) from the dividend, attach it to 179 and continue: 1795 / 326

On to step 6:
1795 divided by 326 is 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 885.0
Deduct 1630 from 1795 and we're left with 165.
Append the next digit (7) from the dividend to 165 and continue with: 1657 / 326

On to step 7:
When dividing 1657 by 326, we get 5 with a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 8855.0
Subtract 1630 from 1657 to get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 326

Advancing to step 8:
326 can be fit into 278 0 times, resulting in a remainder of 278.
Record the quotient 0 as the next digit in the result. 
Result so far: 88550.0
If we subtract 0 from 278, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 9:
The number 326 fits into 2780 8 times, leaving a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 88550.8
If we subtract 2608 from 2780, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 10:
1720 divided by 326 is 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 88550.85
Subtract 1630 from 1720 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
900 divided by 326 is 2 with a remainder of 248.
Use 2 as the next digit of our solution. 
Result so far: 88550.852
If we subtract 652 from 900, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 12:
2480 divided by 326 is 7 with a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 88550.8527
If we subtract 2282 from 2480, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 13:
When dividing 1980 by 326, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 88550.85276
The remainder is 24 after subtracting 1956 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
The number 326 fits into 240 0 times, leaving a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 88550.85276
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 15:
326 can be fit into 2400 7 times, resulting in a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 88550.8527607
Deduct 2282 from 2400 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 16:
When dividing 1180 by 326, we get 3 with a remainder of 202.
The next digit of our result is 3. 
Result so far: 88550.85276073
If we take 978 away from 1180, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final result is 88550.85276073 with a remainder of 2.02e-07.
