We look at the division of 85866225 by 326 
The aim is to understand the frequency of 326 in 85866225.

Going ahead to step 1:
326 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 326

Going ahead to step 2:
The number 326 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 326

Step 3:
326 can be fit into 858 2 times, resulting in a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 652 from 858 leaves us with 206.
Include the next digit (6) from the dividend after 206, then repeat: 2066 / 326

On to step 4:
When dividing 2066 by 326, we get 6 with a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 1956 from 2066 and we're left with 110.
Include the next digit (6) from the dividend after 110, then repeat: 1106 / 326

Advancing to step 5:
When dividing 1106 by 326, we get 3 with a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 263.0
Deduct 978 from 1106 and we're left with 128.
Fetch the next digit (2) from the dividend, attach it to 128 and continue: 1282 / 326

Let's proceed to step 6:
1282 divided by 326 is 3 with a remainder of 304.
Use 3 as the next digit of our solution. 
Result so far: 2633.0
Deduct 978 from 1282 and we're left with 304.
Grab the next digit (2) from the dividend, add it to 304, then carry on: 3042 / 326

Let's proceed to step 7:
326 goes into 3042 9 times with a remainder of 108.
The number 9 becomes the next digit in our result. 
Result so far: 26339.0
Deduct 2934 from 3042 and we're left with 108.
Fetch the next digit (5) from the dividend, attach it to 108 and continue: 1085 / 326

Let's proceed to step 8:
When dividing 1085 by 326, we get 3 with a remainder of 107.
The number 3 becomes the next digit in our result. 
Result so far: 263393.0
If we subtract 978 from 1085, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 9:
When dividing 1070 by 326, we get 3 with a remainder of 92.
The next digit of our result is 3. 
Result so far: 263393.3
If we subtract 978 from 1070, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
If we divide 920 by 326, we get 2 and a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 263393.32
Subtracting 652 from 920 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
The number 326 fits into 2680 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 263393.328
Subtract 2608 from 2680 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
720 divided by 326 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 263393.3282
The remainder is 68 after subtracting 652 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
The number 326 fits into 680 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 263393.32822
The remainder is 28 after subtracting 652 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 263393.32822, with a leftover of 2.8e-05.
