We divide 447891 by 45
The aim is to understand the frequency of 45 in 447891.

Let's proceed to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 45

Let's proceed to step 2:
45 goes into 44 0 times with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 45

Let's proceed to step 3:
447 divided by 45 is 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 405 from 447 and we're left with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 45

Step 4:
45 can be fit into 428 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
The remainder is 23 after subtracting 405 from 428.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

Step 5:
If we divide 239 by 45, we get 5 and a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 995.0
The remainder is 14 after subtracting 225 from 239.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 45

Step 6:
When dividing 141 by 45, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 9953.0
Subtract 135 from 141 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 45 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 9953.1
If we subtract 45 from 60, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 9953.13
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 45 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 9953.133
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 9953.133, and the remainder is 0.0015.
