Let's divide 631460 by 45
The aim is to understand the frequency of 45 in 631460.

Moving on to step 1:
45 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 45

Moving on to step 2:
63 divided by 45 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 63, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 45

Moving on to step 3:
45 goes into 181 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 1 after subtracting 180 from 181.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 45

Advancing to step 4:
If we divide 14 by 45, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtract 0 from 14 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 45

Advancing to step 5:
If we divide 146 by 45, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1403.0
Subtracting 135 from 146 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 45

Let's proceed to step 6:
The number 45 fits into 110 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 14032.0
Deduct 90 from 110 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 14032.4
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 14032.44
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 14032.44, with a leftover of 0.02.
