We're dividing 885846 by 45 
The aim is to understand the frequency of 45 in 885846.

Moving on to step 1:
8 divided by 45 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 45

Let's proceed to step 2:
When dividing 88 by 45, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 88, we end up with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 45

Step 3:
The number 45 fits into 435 9 times, leaving a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 405 from 435 to get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 45

Let's proceed to step 4:
The number 45 fits into 308 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 196.0
The remainder is 38 after subtracting 270 from 308.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 45

On to step 5:
45 goes into 384 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1968.0
Subtract 360 from 384 to get 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 45

Let's proceed to step 6:
When dividing 246 by 45, we get 5 with a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 19685.0
Subtract 225 from 246 to 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.

Step 7:
210 divided by 45 is 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 19685.4
Deduct 180 from 210 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.

Advancing to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 19685.46
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.

Let's proceed to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
The next digit of our result is 6. 
Result so far: 19685.466
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.

After the division, we end up with 19685.466 and a remainder of 0.003.
