844998 ÷ 45 
The aim is to understand the frequency of 45 in 844998.

Going ahead to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 45

Advancing to step 2:
If we divide 84 by 45, we get 1 and a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 84, we end up with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 45

Step 3:
394 divided by 45 is 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 360 from 394 leaves us with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 45

Going ahead to step 4:
45 can be fit into 349 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we subtract 315 from 349, we get 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 45

On to step 5:
45 can be fit into 349 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 1877.0
If we subtract 315 from 349, we get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 45

Going ahead to step 6:
45 goes into 348 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 18777.0
If we take 315 away from 348, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
45 goes into 330 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 18777.7
The remainder is 15 after subtracting 315 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 18777.73
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18777.733
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 18777.733 and a remainder of 0.0015.
