513280 ÷ 39 
We want to divide 513280 by 39.

Advancing to step 1:
5 divided by 39 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 39

Moving on to step 2:
When dividing 51 by 39, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 51 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 39

Going ahead to step 3:
39 can be fit into 123 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 13.0
If we take 117 away from 123, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 39

Step 4:
The number 39 fits into 62 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Deduct 39 from 62 and we're left with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 39

Advancing to step 5:
When dividing 238 by 39, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1316.0
Deduct 234 from 238 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 39

Going ahead to step 6:
39 goes into 40 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 13161.0
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.

Going ahead to step 7:
The number 39 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13161.0
If we subtract 0 from 10, we 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.

Let's proceed to step 8:
When dividing 100 by 39, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 13161.02
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 9:
The number 39 fits into 220 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 13161.025
Deduct 195 from 220 and we're left 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.

Let's proceed to step 10:
When dividing 250 by 39, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 13161.0256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 39 fits into 160 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 13161.02564
The remainder is 4 after subtracting 156 from 160.
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 12:
If we divide 40 by 39, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 13161.025641
Subtracting 39 from 40 leaves us 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.

Let's proceed to step 13:
When dividing 10 by 39, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13161.025641
Deduct 0 from 10 and we're left 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.

Let's proceed to step 14:
When dividing 100 by 39, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 13161.02564102
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.

After the division, we end up with 13161.02564102 and a remainder of 2.2e-08.
