We look at the division of 439391 by 79 
Let's see how many times 79 fits into 439391.

Let's proceed to step 1:
When dividing 4 by 79, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 79

On to step 2:
The number 79 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 79

Let's proceed to step 3:
439 divided by 79 is 5 with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 395 from 439 and we're left with 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 79

Going ahead to step 4:
If we divide 443 by 79, we get 5 and a remainder of 48.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 395 from 443 leaves us with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 79

Advancing to step 5:
79 can be fit into 489 6 times, resulting in a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 556.0
The remainder is 15 after subtracting 474 from 489.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 79

On to step 6:
If we divide 151 by 79, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 5561.0
Subtract 79 from 151 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
If we divide 720 by 79, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 5561.9
Deduct 711 from 720 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
If we divide 90 by 79, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 5561.91
If we subtract 79 from 90, we 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.

Going ahead to step 9:
If we divide 110 by 79, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 5561.911
Subtract 79 from 110 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 5561.911, and the remainder is 0.0031.
