We're dividing 503447 by 48 
The aim is to understand the frequency of 48 in 503447.

Step 1:
48 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 48

Going ahead to step 2:
When dividing 50 by 48, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 48 from 50 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 48

Let's proceed to step 3:
If we divide 23 by 48, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 48

Let's proceed to step 4:
When dividing 234 by 48, we get 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 192 from 234, we get 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 48

Step 5:
424 divided by 48 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1048.0
Deduct 384 from 424 and we're left with 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 48

On to step 6:
407 divided by 48 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 10488.0
If we take 384 away from 407, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
If we divide 230 by 48, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 10488.4
Subtract 192 from 230 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
If we divide 380 by 48, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 10488.47
Subtract 336 from 380 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
48 goes into 440 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 10488.479
Subtract 432 from 440 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.

Going ahead to step 10:
48 goes into 80 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 10488.4791
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.

Step 11:
If we divide 320 by 48, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 10488.47916
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.

On to step 12:
48 goes into 320 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 10488.479166
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.

The final outcome is 10488.479166, with a leftover of 3.2e-06.
