150519 ÷ 39 
We want to figure out the number of times 150519 can be divided by 39.

On to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 39

On to step 2:
If we divide 15 by 39, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 39

Let's proceed to step 3:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 117 from 150, we get 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 39

Let's proceed to step 4:
335 divided by 39 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 312 from 335 to get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 39

Advancing to step 5:
39 goes into 231 5 times with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 385.0
Deduct 195 from 231 and we're left with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 39

On to step 6:
If we divide 369 by 39, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 3859.0
Deduct 351 from 369 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3859.4
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
39 goes into 240 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3859.46
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 3859.461
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
210 divided by 39 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3859.4615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
39 goes into 150 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 3859.46153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
When dividing 330 by 39, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 3859.461538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3859.4615384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
39 goes into 240 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3859.46153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 3859.46153846 with a remaining 6e-09.
