We're dividing 743939 by 48 
We're looking to find how many times 48 goes into 743939.

Moving on to step 1:
When dividing 7 by 48, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 48

Going ahead to step 2:
If we divide 74 by 48, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 48 from 74 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 48

Moving on to step 3:
If we divide 263 by 48, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 15.0
If we take 240 away from 263, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 48

Advancing to step 4:
48 can be fit into 239 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 154.0
The remainder is 47 after subtracting 192 from 239.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 48

Step 5:
When dividing 473 by 48, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 1549.0
Subtracting 432 from 473 leaves us with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 48

Step 6:
48 can be fit into 419 8 times, resulting in a remainder of 35.
The next digit of our result is 8. 
Result so far: 15498.0
The remainder is 35 after subtracting 384 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
48 can be fit into 350 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 15498.7
The remainder is 14 after subtracting 336 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 48 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 15498.72
The remainder is 44 after subtracting 96 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
440 divided by 48 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 15498.729
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 48 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 15498.7291
The remainder is 32 after subtracting 48 from 80.
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:
320 divided by 48 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 15498.72916
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
48 goes into 320 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 15498.729166
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.

After the division, we end up with 15498.729166 and a remainder of 3.2e-06.
