503839 ÷ 79 
We want to divide 503839 by 79.

Step 1:
If we divide 5 by 79, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 79

Advancing to step 2:
79 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 79

On to step 3:
79 goes into 503 6 times with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 474 from 503, we get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 79

Moving on to step 4:
When dividing 298 by 79, we get 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 237 from 298 to get 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 79

Moving on to step 5:
If we divide 613 by 79, we get 7 and a remainder of 60.
The next digit of our result is 7. 
Result so far: 637.0
Deduct 553 from 613 and we're left with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 79

Step 6:
When dividing 609 by 79, we get 7 with a remainder of 56.
The next digit of our result is 7. 
Result so far: 6377.0
Subtracting 553 from 609 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
79 can be fit into 560 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 6377.7
If we subtract 553 from 560, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 79 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 6377.7
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
700 divided by 79 is 8 with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 6377.708
Subtract 632 from 700 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 79 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 6377.7088
Subtract 632 from 680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 6377.7088 and a remainder of 0.00048.
