Let's divide 672717 by 45
The aim is to understand the frequency of 45 in 672717.

Advancing to step 1:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 45

Advancing to step 2:
If we divide 67 by 45, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 67 to get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 45

On to step 3:
When dividing 222 by 45, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 180 from 222 to get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 45

Step 4:
The number 45 fits into 427 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 149.0
Subtracting 405 from 427 leaves us with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 45

On to step 5:
45 goes into 221 4 times with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 1494.0
Subtract 180 from 221 to get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 45

Advancing to step 6:
45 can be fit into 417 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 14949.0
Subtracting 405 from 417 leaves us 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.

On to step 7:
When dividing 120 by 45, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 14949.2
Subtract 90 from 120 to get 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 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 14949.26
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 14949.266
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 14949.266 and a remainder of 0.003.
