We divide 373458 by 45
The aim is to understand the frequency of 45 in 373458.

On to step 1:
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: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 45

Advancing to step 2:
When dividing 37 by 45, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 45

Let's proceed to step 3:
The number 45 fits into 373 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 360 from 373, we get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 45

Moving on to step 4:
45 goes into 134 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 90 from 134, we get 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 45

Moving on to step 5:
If we divide 445 by 45, we get 9 and a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 829.0
If we subtract 405 from 445, we get 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 45

Step 6:
45 goes into 408 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 8299.0
Subtracting 405 from 408 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 45 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8299.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 8299.06
Subtracting 270 from 300 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.

On to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 8299.066
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.

In conclusion, the division gives 8299.066 with a balance of 0.003.
