780708 ÷ 45 
The aim is to understand the frequency of 45 in 780708.

Step 1:
45 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 45

Let's proceed to step 2:
When dividing 78 by 45, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 78, we get 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 45

Moving on to step 3:
45 can be fit into 330 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 17.0
If we take 315 away from 330, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 45

Step 4:
45 goes into 157 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 173.0
The remainder is 22 after subtracting 135 from 157.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 45

Let's proceed to step 5:
220 divided by 45 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1734.0
Deduct 180 from 220 and we're left with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 45

Step 6:
45 can be fit into 408 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 17349.0
The remainder is 3 after subtracting 405 from 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 45 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 17349.0
Deduct 0 from 30 and we're left 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.

Going ahead to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 17349.06
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
45 goes into 300 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 17349.066
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 17349.066 with a remaining 0.003.
