629271 ÷ 45 
The aim is to understand the frequency of 45 in 629271.

Moving on to step 1:
45 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 45

On to step 2:
45 goes into 62 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 62 leaves us with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 45

Moving on to step 3:
The number 45 fits into 179 3 times, leaving a remainder of 44.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 135 from 179 to get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 45

Let's proceed to step 4:
45 goes into 442 9 times with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 405 from 442 to get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 45

On to step 5:
377 divided by 45 is 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 1398.0
The remainder is 17 after subtracting 360 from 377.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 45

Going ahead to step 6:
45 can be fit into 171 3 times, resulting in a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 13983.0
The remainder is 36 after subtracting 135 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
The number 45 fits into 360 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 13983.8
If we take 360 away from 360, we end up 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.

Let's proceed to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13983.8
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.

Advancing to step 9:
When dividing 0 by 45, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13983.8
If we take 0 away from 0, we end up 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.

Our division results in 13983.8 with a remaining 0.0.
