3030454 divided by 723 
The aim is to understand the frequency of 723 in 3030454.

On to step 1:
723 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 723

Moving on to step 2:
30 divided by 723 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 723

Moving on to step 3:
The number 723 fits into 303 0 times, leaving a remainder of 303.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 303, we end up with 303.
Bring next digit (0) of the dividend behind the 303 and repeat the process: 3030 / 723

On to step 4:
723 goes into 3030 4 times with a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2892 away from 3030, we end up with 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 723

Advancing to step 5:
When dividing 1384 by 723, we get 1 with a remainder of 661.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 723 from 1384, we get 661.
Fetch the next digit (5) from the dividend, attach it to 661 and continue: 6615 / 723

Step 6:
723 goes into 6615 9 times with a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
The remainder is 108 after subtracting 6507 from 6615.
Bring next digit (4) of the dividend behind the 108 and repeat the process: 1084 / 723

Step 7:
When dividing 1084 by 723, we get 1 with a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 4191.0
Subtracting 723 from 1084 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 8:
When dividing 3610 by 723, we get 4 with a remainder of 718.
The number 4 becomes the next digit in our result. 
Result so far: 4191.4
If we take 2892 away from 3610, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 9:
7180 divided by 723 is 9 with a remainder of 673.
The next digit of our result is 9. 
Result so far: 4191.49
Subtract 6507 from 7180 to get 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Step 10:
6730 divided by 723 is 9 with a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 4191.499
If we take 6507 away from 6730, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

The final outcome is 4191.499, with a leftover of 0.0223.
