We're dividing 914175 by 45 
The aim is to understand the frequency of 45 in 914175.

Moving on to step 1:
9 divided by 45 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 45

Moving on to step 2:
The number 45 fits into 91 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 90 from 91 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 45

Moving on to step 3:
If we divide 14 by 45, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 14 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 45

Let's proceed to step 4:
The number 45 fits into 141 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 203.0
The remainder is 6 after subtracting 135 from 141.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 45

Step 5:
45 can be fit into 67 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 2031.0
Subtracting 45 from 67 leaves us with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 45

Let's proceed to step 6:
45 goes into 225 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20315.0
Deduct 225 from 225 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 20315.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20315.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 20315.0 with a remainder of 0.0.
