720674 divided by 45 
The aim is to understand the frequency of 45 in 720674.

Moving on to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 45

Let's proceed to step 2:
When dividing 72 by 45, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 72, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 45

On to step 3:
45 can be fit into 270 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 270 away from 270, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 45

Let's proceed to step 4:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 45

Step 5:
45 can be fit into 67 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1601.0
If we subtract 45 from 67, we get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 45

Step 6:
The number 45 fits into 224 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 16014.0
Subtracting 180 from 224 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
45 can be fit into 440 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 16014.9
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 16014.97
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
350 divided by 45 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 16014.977
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 16014.977, and the remainder is 0.0035.
