We look at the division of 868639 by 48 
The aim is to understand the frequency of 48 in 868639.

Let's proceed to step 1:
48 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 48

On to step 2:
48 can be fit into 86 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 48 from 86 and we're left with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 48

Step 3:
388 divided by 48 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 18.0
If we take 384 away from 388, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 48

On to step 4:
48 goes into 46 0 times with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 48

On to step 5:
If we divide 463 by 48, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1809.0
Deduct 432 from 463 and we're left with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 48

Let's proceed to step 6:
319 divided by 48 is 6 with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 18096.0
If we take 288 away from 319, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 48 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 18096.6
If we subtract 288 from 310, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
The number 48 fits into 220 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 18096.64
Subtracting 192 from 220 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 48 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 18096.645
The remainder is 40 after subtracting 240 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 48 fits into 400 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 18096.6458
Subtract 384 from 400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
48 goes into 160 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 18096.64583
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
48 can be fit into 160 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 18096.645833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 18096.645833 with a remainder of 1.6e-06.
