439259 ÷ 48 
Let's see how many times 48 fits into 439259.

Step 1:
48 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 48

On to step 2:
48 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of 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

On to step 3:
48 goes into 439 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 432 from 439, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 48

Moving on to step 4:
When dividing 72 by 48, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 91.0
The remainder is 24 after subtracting 48 from 72.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 48

On to step 5:
48 can be fit into 245 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 915.0
The remainder is 5 after subtracting 240 from 245.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 48

Advancing to step 6:
The number 48 fits into 59 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 9151.0
Subtract 48 from 59 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
48 can be fit into 110 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 9151.2
Deduct 96 from 110 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
48 can be fit into 140 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 9151.22
If we subtract 96 from 140, we 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.

The quotient of the division is 9151.22, and the remainder is 0.044.
