907225 divided by 45 
The aim is to understand the frequency of 45 in 907225.

Let's proceed to step 1:
45 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 45

Moving on to step 2:
When dividing 90 by 45, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 90 from 90.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 45

Advancing to step 3:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

Moving on to step 4:
When dividing 72 by 45, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 201.0
Subtracting 45 from 72 leaves us with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 45

Step 5:
272 divided by 45 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2016.0
The remainder is 2 after subtracting 270 from 272.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 45

Let's proceed to step 6:
If we divide 25 by 45, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 20160.0
If we take 0 away from 25, we end up 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.

Advancing to step 7:
250 divided by 45 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 20160.5
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
45 goes into 250 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 20160.55
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 20160.55, and the remainder is 0.025.
