We divide 503968 by 39
Let's see how many times 39 fits into 503968.

Going ahead to step 1:
5 divided by 39 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 39

Advancing to step 2:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 39 from 50 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 39

Let's proceed to step 3:
The number 39 fits into 113 2 times, leaving a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 78 from 113 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 39

On to step 4:
The number 39 fits into 359 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 8 after subtracting 351 from 359.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 39

Advancing to step 5:
If we divide 86 by 39, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1292.0
If we take 78 away from 86, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 39

Let's proceed to step 6:
The number 39 fits into 88 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12922.0
If we take 78 away from 88, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 39 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 12922.2
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
The number 39 fits into 220 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12922.25
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
39 goes into 250 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 12922.256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 39, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 12922.2564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 12922.25641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
39 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12922.25641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 39, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 12922.2564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
220 divided by 39 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12922.25641025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 12922.25641025, with a leftover of 2.5e-08.
