Let's divide 881301 by 45
The aim is to understand the frequency of 45 in 881301.

Advancing to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 45

On to step 2:
The number 45 fits into 88 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 88, we get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 45

Advancing to step 3:
45 goes into 431 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 405 from 431 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 45

Moving on to step 4:
45 goes into 263 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Subtract 225 from 263 to get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 45

Advancing to step 5:
380 divided by 45 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 1958.0
If we subtract 360 from 380, we get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 45

Going ahead to step 6:
201 divided by 45 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 19584.0
If we subtract 180 from 201, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
45 can be fit into 210 4 times, resulting in a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 19584.4
Subtract 180 from 210 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.

Step 8:
300 divided by 45 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 19584.46
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:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 19584.466
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.

Our division results in 19584.466 with a remaining 0.003.
