We look at the division of 449897 by 48 
The aim is to understand the frequency of 48 in 449897.

On to step 1:
If we divide 4 by 48, we get 0 and 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.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 48

Advancing to step 2:
48 goes into 44 0 times with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 48

Let's proceed to step 3:
449 divided by 48 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 432 from 449 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 48

On to step 4:
178 divided by 48 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we subtract 144 from 178, we get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 48

On to step 5:
48 can be fit into 349 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 937.0
Subtract 336 from 349 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 48

Let's proceed to step 6:
The number 48 fits into 137 2 times, leaving a remainder of 41.
The next digit of our result is 2. 
Result so far: 9372.0
If we subtract 96 from 137, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
The number 48 fits into 410 8 times, leaving a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 9372.8
The remainder is 26 after subtracting 384 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 48, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 9372.85
Subtracting 240 from 260 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.

Advancing to step 9:
The number 48 fits into 200 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 9372.854
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 48, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 9372.8541
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
48 goes into 320 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 9372.85416
If we take 288 away from 320, we end up 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.

Moving on to step 12:
When dividing 320 by 48, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 9372.854166
Deduct 288 from 320 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.

In conclusion, the division gives 9372.854166 with a balance of 3.2e-06.
