885548 ÷ 45 
The aim is to understand the frequency of 45 in 885548.

Going ahead to step 1:
45 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 45

Advancing to step 2:
If we divide 88 by 45, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 88 to get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 45

Let's proceed to step 3:
45 goes into 435 9 times with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 405 away from 435, we end up with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 45

Moving on to step 4:
45 can be fit into 305 6 times, resulting in a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 196.0
The remainder is 35 after subtracting 270 from 305.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 45

Moving on to step 5:
45 can be fit into 354 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 1967.0
If we take 315 away from 354, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 45

Going ahead to step 6:
The number 45 fits into 398 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 19678.0
Subtract 360 from 398 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 45 fits into 380 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 19678.8
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 19678.84
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 19678.844
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 19678.844 with a remainder of 0.002.
