We look at the division of 829833 by 45 
The aim is to understand the frequency of 45 in 829833.

Moving on to step 1:
The number 45 fits into 8 0 times, leaving 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 (2) from the dividend and append it to 8, then repeat: 82 / 45

Step 2:
45 can be fit into 82 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 45 from 82 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 45

On to step 3:
The number 45 fits into 379 8 times, leaving a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 19 after subtracting 360 from 379.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 45

Advancing to step 4:
If we divide 198 by 45, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we subtract 180 from 198, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 45

Let's proceed to step 5:
The number 45 fits into 183 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 1844.0
If we take 180 away from 183, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 45

On to step 6:
When dividing 33 by 45, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 18440.0
If we take 0 away from 33, 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.

Going ahead to step 7:
The number 45 fits into 330 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 18440.7
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.

Going ahead to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18440.73
If we take 135 away from 150, we end up 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.

Advancing to step 9:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18440.733
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.

The quotient of the division is 18440.733, and the remainder is 0.0015.
