We're dividing 439031 by 48 
The aim is to understand the frequency of 48 in 439031.

Let's proceed to step 1:
4 divided by 48 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 48

Moving on to step 2:
48 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 48

Going ahead to step 3:
If we divide 439 by 48, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 432 from 439, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 48

On to step 4:
The number 48 fits into 70 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 91.0
The remainder is 22 after subtracting 48 from 70.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 48

Step 5:
48 can be fit into 223 4 times, resulting in a remainder of 31.
The next digit of our result is 4. 
Result so far: 914.0
The remainder is 31 after subtracting 192 from 223.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 48

Moving on to step 6:
The number 48 fits into 311 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 9146.0
Deduct 288 from 311 and we're left 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.

Advancing to step 7:
48 goes into 230 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 9146.4
The remainder is 38 after subtracting 192 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
If we divide 380 by 48, we get 7 and a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 9146.47
Deduct 336 from 380 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
The number 48 fits into 440 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 9146.479
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 48, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 9146.4791
If we subtract 48 from 80, 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.

Going ahead to step 11:
48 goes into 320 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 9146.47916
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.

Going ahead to step 12:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 9146.479166
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.

The final outcome is 9146.479166, with a leftover of 3.2e-06.
