864033 ÷ 45 
The aim is to understand the frequency of 45 in 864033.

Advancing to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 45

Step 2:
When dividing 86 by 45, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 86 leaves us with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 45

Going ahead to step 3:
45 can be fit into 414 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 405 from 414 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 45

Step 4:
90 divided by 45 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtract 90 from 90 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 45

Let's proceed to step 5:
When dividing 3 by 45, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 1920.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 45

Advancing to step 6:
45 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 19200.0
The remainder is 33 after subtracting 0 from 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:
When dividing 330 by 45, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 19200.7
If we subtract 315 from 330, we get 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 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 19200.73
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.

Step 9:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 19200.733
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.

The quotient of the division is 19200.733, and the remainder is 0.0015.
