Let's divide 171224 by 48
The aim is to understand the frequency of 48 in 171224.

Advancing to step 1:
When dividing 1 by 48, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 48

Moving on to step 2:
48 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 48

Moving on to step 3:
171 divided by 48 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 144 from 171 to get 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 48

Step 4:
48 goes into 272 5 times with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 32 after subtracting 240 from 272.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 48

Moving on to step 5:
48 can be fit into 322 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 356.0
The remainder is 34 after subtracting 288 from 322.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 48

Going ahead to step 6:
344 divided by 48 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 3567.0
Subtract 336 from 344 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 48, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 3567.1
Subtracting 48 from 80 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.

On to step 8:
If we divide 320 by 48, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 3567.16
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.

Moving on to step 9:
If we divide 320 by 48, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 3567.166
If we subtract 288 from 320, we 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.

The final result is 3567.166 with a remainder of 0.0032.
