4383139 ÷ 348 
Let's see how many times 348 fits into 4383139.

Moving on to step 1:
When dividing 4 by 348, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 348

Going ahead to step 2:
If we divide 43 by 348, we get 0 and 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 (8) from the dividend to 43 and continue with: 438 / 348

Step 3:
438 divided by 348 is 1 with a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 90 after subtracting 348 from 438.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 348

On to step 4:
If we divide 903 by 348, we get 2 and a remainder of 207.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 696 away from 903, we end up with 207.
Include the next digit (1) from the dividend after 207, then repeat: 2071 / 348

Advancing to step 5:
The number 348 fits into 2071 5 times, leaving a remainder of 331.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 1740 from 2071, we get 331.
Bring next digit (3) of the dividend behind the 331 and repeat the process: 3313 / 348

On to step 6:
When dividing 3313 by 348, we get 9 with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 1259.0
Subtracting 3132 from 3313 leaves us with 181.
Append the next digit (9) from the dividend to 181 and continue with: 1819 / 348

Let's proceed to step 7:
348 goes into 1819 5 times with a remainder of 79.
The next digit of our result is 5. 
Result so far: 12595.0
If we subtract 1740 from 1819, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 8:
348 can be fit into 790 2 times, resulting in a remainder of 94.
The next digit of our result is 2. 
Result so far: 12595.2
If we subtract 696 from 790, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
If we divide 940 by 348, we get 2 and a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 12595.22
Subtracting 696 from 940 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final outcome is 12595.22, with a leftover of 0.244.
