We're dividing 490466 by 48 
The aim is to understand the frequency of 48 in 490466.

Let's proceed to step 1:
48 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 48

Moving on to step 2:
48 can be fit into 49 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 48 from 49 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 48

Advancing to step 3:
The number 48 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 48

Step 4:
104 divided by 48 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 96 from 104 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 48

Step 5:
When dividing 86 by 48, we get 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
Deduct 48 from 86 and we're left with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 48

Moving on to step 6:
When dividing 386 by 48, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 10218.0
If we take 384 away from 386, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 48, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10218.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 48 fits into 200 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 10218.04
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 48, we get 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 10218.041
Deduct 48 from 80 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
48 goes into 320 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 10218.0416
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 48 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 10218.04166
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 10218.04166, with a leftover of 3.2e-05.
