We divide 728022 by 45
The aim is to understand the frequency of 45 in 728022.

Step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

Advancing to step 2:
45 goes into 72 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 72, we get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 45

Let's proceed to step 3:
45 can be fit into 278 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 8 after subtracting 270 from 278.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 45

Moving on to step 4:
45 can be fit into 80 1 times, resulting in a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Deduct 45 from 80 and we're left with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 45

Advancing to step 5:
If we divide 352 by 45, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1617.0
Subtract 315 from 352 to get 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 45

Step 6:
If we divide 372 by 45, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 16178.0
Deduct 360 from 372 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 45 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 16178.2
Subtracting 90 from 120 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 16178.26
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
300 divided by 45 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 16178.266
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 16178.266 with a remainder of 0.003.
