We're dividing 429376 by 45 
The aim is to understand the frequency of 45 in 429376.

Let's proceed to step 1:
45 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 45

On to step 2:
The number 45 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 45

Going ahead to step 3:
The number 45 fits into 429 9 times, leaving a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 405 from 429 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 45

Let's proceed to step 4:
If we divide 243 by 45, we get 5 and a remainder of 18.
The next digit of our result is 5. 
Result so far: 95.0
If we take 225 away from 243, we end up with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 45

Advancing to step 5:
187 divided by 45 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
If we take 180 away from 187, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 45

Going ahead to step 6:
If we divide 76 by 45, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 9541.0
If we take 45 away from 76, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
If we divide 310 by 45, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 9541.6
Deduct 270 from 310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 9541.68
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 9541.688
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 9541.688 and a remainder of 0.004.
