We divide 509515 by 39
We want to figure out the number of times 509515 can be divided by 39.

Let's proceed to step 1:
The number 39 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 39

Let's proceed to step 2:
If we divide 50 by 39, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 39 from 50, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 39

Let's proceed to step 3:
When dividing 119 by 39, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 117 from 119 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 39

Going ahead to step 4:
When dividing 25 by 39, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 39

Moving on to step 5:
39 goes into 251 6 times with a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 1306.0
The remainder is 17 after subtracting 234 from 251.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 39

Going ahead to step 6:
The number 39 fits into 175 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 13064.0
If we subtract 156 from 175, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 39, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 13064.4
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 39, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 13064.48
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
280 divided by 39 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 13064.487
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
When dividing 70 by 39, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 13064.4871
Deduct 39 from 70 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 13064.48717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 13064.487179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 13064.4871794
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
When dividing 340 by 39, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 13064.48717948
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 13064.48717948 with a remainder of 2.8e-08.
