We're dividing 368973 by 45 
The aim is to understand the frequency of 45 in 368973.

Let's proceed to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 45

Advancing to step 2:
36 divided by 45 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 45

On to step 3:
The number 45 fits into 368 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 360 from 368 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 45

Let's proceed to step 4:
45 goes into 89 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 45 from 89, we get 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 45

Going ahead to step 5:
45 can be fit into 447 9 times, resulting in a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
Deduct 405 from 447 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 45

Step 6:
If we divide 423 by 45, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 8199.0
If we take 405 away from 423, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
45 can be fit into 180 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 8199.4
If we subtract 180 from 180, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8199.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8199.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8199.4 and a remainder of 0.0.
