140943 divided by 48 
The aim is to understand the frequency of 48 in 140943.

On to step 1:
When dividing 1 by 48, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 48

Step 2:
48 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 48

Let's proceed to step 3:
48 goes into 140 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 44 after subtracting 96 from 140.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 48

Let's proceed to step 4:
48 goes into 449 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 432 from 449 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 48

Going ahead to step 5:
48 can be fit into 174 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 293.0
If we take 144 away from 174, we end up with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 48

Step 6:
48 can be fit into 303 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 2936.0
The remainder is 15 after subtracting 288 from 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 48, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2936.3
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 48 fits into 60 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2936.31
Deduct 48 from 60 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 2936.312
If we take 96 away from 120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
240 divided by 48 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2936.3125
Deduct 240 from 240 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2936.3125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
0 divided by 48 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2936.3125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2936.3125 and a remainder of 0.0.
