We look at the division of 93327789 by 45 
The aim is to understand the frequency of 45 in 93327789.

Let's proceed to step 1:
9 divided by 45 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 45

On to step 2:
If we divide 93 by 45, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 90 from 93 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 45

On to step 3:
When dividing 33 by 45, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 33, we get 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 45

On to step 4:
45 can be fit into 332 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 207.0
Subtract 315 from 332 to get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 45

Step 5:
45 goes into 177 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 2073.0
The remainder is 42 after subtracting 135 from 177.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 45

On to step 6:
When dividing 427 by 45, we get 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 20739.0
If we subtract 405 from 427, we get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 45

Step 7:
If we divide 228 by 45, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 207395.0
Subtracting 225 from 228 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 45

Step 8:
45 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 2073950.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
45 can be fit into 390 8 times, resulting in a remainder of 30.
The next digit of our result is 8. 
Result so far: 2073950.8
If we subtract 360 from 390, we 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.

Moving on to step 10:
45 goes into 300 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 2073950.86
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 11:
When dividing 300 by 45, we get 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 2073950.866
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.

The final result is 2073950.866 with a remainder of 0.003.
