Let's divide 507780 by 39
We're looking to find how many times 39 goes into 507780.

On to step 1:
39 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 39

Step 2:
When dividing 50 by 39, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 11 after subtracting 39 from 50.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 39

Moving on to step 3:
117 divided by 39 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 0 after subtracting 117 from 117.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 39

Let's proceed to step 4:
The number 39 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 39

Moving on to step 5:
78 divided by 39 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1302.0
Deduct 78 from 78 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 39

Let's proceed to step 6:
If we divide 0 by 39, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13020.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 39, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13020.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
39 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13020.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 13020.0 with a balance of 0.0.
