We look at the division of 871735 by 48 
The aim is to understand the frequency of 48 in 871735.

Step 1:
When dividing 8 by 48, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 48

Advancing to step 2:
48 goes into 87 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 48 from 87, we get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 48

Advancing to step 3:
48 goes into 391 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 384 from 391 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 48

On to step 4:
The number 48 fits into 77 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 181.0
Deduct 48 from 77 and we're left with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 48

Moving on to step 5:
When dividing 293 by 48, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 1816.0
If we take 288 away from 293, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 48

Let's proceed to step 6:
If we divide 55 by 48, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 18161.0
The remainder is 7 after subtracting 48 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 48 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 18161.1
Deduct 48 from 70 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
When dividing 220 by 48, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 18161.14
Deduct 192 from 220 and we're left 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.

Step 9:
48 goes into 280 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 18161.145
Subtracting 240 from 280 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 48, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 18161.1458
If we take 384 away from 400, we end up with 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 11:
48 goes into 160 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 18161.14583
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 48, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 18161.145833
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 18161.145833 with a remaining 1.6e-06.
