We divide 515619 by 39
We're looking to find how many times 39 goes into 515619.

On to step 1:
39 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 39

On to step 2:
51 divided by 39 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 39 from 51.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 39

Advancing to step 3:
125 divided by 39 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 117 away from 125, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 39

Let's proceed to step 4:
The number 39 fits into 86 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
If we take 78 away from 86, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 39

Going ahead to step 5:
If we divide 81 by 39, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1322.0
Subtract 78 from 81 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 39

Step 6:
When dividing 39 by 39, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 13221.0
Subtracting 39 from 39 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:
39 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13221.0
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:
0 divided by 39 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13221.0
Subtract 0 from 0 to 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.

Our division results in 13221.0 with a remaining 0.0.
