Let's divide 452910 by 68
The aim is to understand the frequency of 68 in 452910.

Moving on to step 1:
If we divide 4 by 68, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 68

Moving on to step 2:
The number 68 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 68

Step 3:
68 can be fit into 452 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 408 from 452 leaves us with 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 68

Going ahead to step 4:
449 divided by 68 is 6 with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 408 away from 449, we end up with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 68

Step 5:
When dividing 411 by 68, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 666.0
If we take 408 away from 411, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 68

Step 6:
If we divide 30 by 68, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 6660.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
68 goes into 300 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 6660.4
Deduct 272 from 300 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
280 divided by 68 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 6660.44
Subtracting 272 from 280 leaves us 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.

Our division results in 6660.44 with a remaining 0.008.
