We divide 489731 by 45
The aim is to understand the frequency of 45 in 489731.

On to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 45

Step 2:
48 divided by 45 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 48, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 45

Let's proceed to step 3:
The number 45 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 45

Let's proceed to step 4:
45 goes into 397 8 times with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 108.0
Deduct 360 from 397 and we're left with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 45

Let's proceed to step 5:
The number 45 fits into 373 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 1088.0
Subtracting 360 from 373 leaves us with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 45

Moving on to step 6:
When dividing 131 by 45, we get 2 with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 10882.0
If we take 90 away from 131, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
45 goes into 410 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 10882.9
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 10882.91
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 10882.911
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 10882.911 with a remainder of 0.0005.
