486223 divided by 45 
The aim is to understand the frequency of 45 in 486223.

Going ahead to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 45

Step 2:
45 goes into 48 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 3 after subtracting 45 from 48.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 45

Step 3:
The number 45 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 36, we get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 45

Let's proceed to step 4:
When dividing 362 by 45, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
The remainder is 2 after subtracting 360 from 362.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 45

Going ahead to step 5:
The number 45 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 1080.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 45

Moving on to step 6:
When dividing 223 by 45, we get 4 with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 10804.0
Subtract 180 from 223 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 45, we get 9 and a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 10804.9
Subtracting 405 from 430 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
250 divided by 45 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10804.95
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
When dividing 250 by 45, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 10804.955
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 10804.955 and a remainder of 0.0025.
