We look at the division of 325992 by 45 
The aim is to understand the frequency of 45 in 325992.

Going ahead to step 1:
3 divided by 45 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 45

Moving on to step 2:
32 divided by 45 is 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 45

Advancing to step 3:
If we divide 325 by 45, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 315 from 325 to get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 45

Going ahead to step 4:
109 divided by 45 is 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 90 from 109 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 45

Step 5:
When dividing 199 by 45, we get 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 724.0
Subtracting 180 from 199 leaves us with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 45

Moving on to step 6:
If we divide 192 by 45, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 7244.0
The remainder is 12 after subtracting 180 from 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
45 goes into 120 2 times with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 7244.2
Subtract 90 from 120 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.

Advancing to step 8:
45 goes into 300 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 7244.26
If we subtract 270 from 300, 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.

Going ahead to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 7244.266
Deduct 270 from 300 and we're left 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.

Our division results in 7244.266 with a remaining 0.003.
