We're dividing 43222462 by 45 
The aim is to understand the frequency of 45 in 43222462.

Step 1:
4 divided by 45 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 45

Moving on to step 2:
If we divide 43 by 45, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 45

Going ahead to step 3:
If we divide 432 by 45, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 405 from 432 to get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 45

Going ahead to step 4:
45 can be fit into 272 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 96.0
Deduct 270 from 272 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 45

Moving on to step 5:
The number 45 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 960.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 45

Step 6:
224 divided by 45 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 9604.0
If we take 180 away from 224, we end up with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 45

Going ahead to step 7:
The number 45 fits into 446 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 96049.0
If we subtract 405 from 446, we get 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 45

Step 8:
45 can be fit into 412 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 960499.0
If we take 405 away from 412, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 45 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 960499.1
Deduct 45 from 70 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
250 divided by 45 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 960499.15
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
45 goes into 250 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 960499.155
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 960499.155, with a leftover of 0.0025.
