458758 ÷ 326 
The aim is to understand the frequency of 326 in 458758.

Going ahead to step 1:
When dividing 4 by 326, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 326

Step 2:
The number 326 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 326

Going ahead to step 3:
If we divide 458 by 326, we get 1 and a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 326 from 458 and we're left with 132.
Append the next digit (7) from the dividend to 132 and continue with: 1327 / 326

Step 4:
When dividing 1327 by 326, we get 4 with a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 1304 away from 1327, we end up with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 326

On to step 5:
The number 326 fits into 235 0 times, leaving a remainder of 235.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtract 0 from 235 to get 235.
Take the next digit (8) from the dividend and append it to 235, then repeat: 2358 / 326

Step 6:
The number 326 fits into 2358 7 times, leaving a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 1407.0
Subtract 2282 from 2358 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 7:
When dividing 760 by 326, we get 2 with a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 1407.2
Subtracting 652 from 760 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 8:
326 goes into 1080 3 times with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 1407.23
Deduct 978 from 1080 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
326 goes into 1020 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1407.233
The remainder is 42 after subtracting 978 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 1407.233 with a balance of 0.0042.
