We're dividing 64353 by 45 
The aim is to understand the frequency of 45 in 64353.

Moving on to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 45

Advancing to step 2:
45 can be fit into 64 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 19 after subtracting 45 from 64.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 45

Let's proceed to step 3:
If we divide 193 by 45, we get 4 and a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 180 away from 193, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 45

Advancing to step 4:
If we divide 135 by 45, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 143.0
Deduct 135 from 135 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 45

Step 5:
If we divide 3 by 45, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 1430.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
The number 45 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1430.0
Subtracting 0 from 30 leaves us 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.

Advancing to step 7:
When dividing 300 by 45, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 1430.06
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.

On to step 8:
When dividing 300 by 45, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 1430.066
Subtract 270 from 300 to 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.

The quotient of the division is 1430.066, and the remainder is 0.003.
