We divide 143439 by 48
We want to figure out the number of times 143439 can be divided by 48.

Going ahead to step 1:
1 divided by 48 is 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.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 48

Going ahead to step 2:
If we divide 14 by 48, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 48

Let's proceed to step 3:
When dividing 143 by 48, we get 2 with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 47 after subtracting 96 from 143.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 48

Let's proceed to step 4:
48 goes into 474 9 times with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 42 after subtracting 432 from 474.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 48

Going ahead to step 5:
The number 48 fits into 423 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 298.0
Subtract 384 from 423 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 48

Moving on to step 6:
48 can be fit into 399 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 2988.0
The remainder is 15 after subtracting 384 from 399.
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:
48 can be fit into 150 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2988.3
If we subtract 144 from 150, we 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.

Step 8:
48 goes into 60 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2988.31
Subtracting 48 from 60 leaves us 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.

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: 2988.312
The remainder is 24 after subtracting 96 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
When dividing 240 by 48, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2988.3125
Subtracting 240 from 240 leaves us 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.

On to step 11:
48 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2988.3125
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 12:
When dividing 0 by 48, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2988.3125
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.

After the division, we end up with 2988.3125 and a remainder of 0.0.
