We look at the division of 427042 by 45 
The aim is to understand the frequency of 45 in 427042.

Moving on to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 45

Let's proceed to step 2:
45 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 45

Let's proceed to step 3:
The number 45 fits into 427 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 22 after subtracting 405 from 427.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 45

Step 4:
If we divide 220 by 45, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtract 180 from 220 to get 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 45

Advancing to step 5:
404 divided by 45 is 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 948.0
The remainder is 44 after subtracting 360 from 404.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 45

Let's proceed to step 6:
The number 45 fits into 442 9 times, leaving a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 9489.0
Subtracting 405 from 442 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
If we divide 370 by 45, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 9489.8
Subtracting 360 from 370 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 9489.82
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 9489.822
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 9489.822, with a leftover of 0.001.
