We look at the division of 666270 by 39 
Let's see how many times 39 fits into 666270.

On to step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 39

Going ahead to step 2:
If we divide 66 by 39, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 66, we end up with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 39

Advancing to step 3:
39 can be fit into 276 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 273 from 276 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 39

Moving on to step 4:
The number 39 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 39

Step 5:
327 divided by 39 is 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 1708.0
Deduct 312 from 327 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 39

Moving on to step 6:
If we divide 150 by 39, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 17083.0
Deduct 117 from 150 and we're left with 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 7:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 17083.8
If we take 312 away from 330, we end up 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.

Going ahead to step 8:
If we divide 180 by 39, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 17083.84
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.

Advancing to step 9:
When dividing 240 by 39, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17083.846
If we take 234 away from 240, we end up 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 10:
60 divided by 39 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 17083.8461
If we take 39 away from 60, we end up 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 11:
39 goes into 210 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17083.84615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
39 can be fit into 150 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 17083.846153
Subtract 117 from 150 to 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.

On to step 13:
When dividing 330 by 39, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 17083.8461538
Subtract 312 from 330 to 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.

Let's proceed to step 14:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 17083.84615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 17083.84615384 with a remaining 2.4e-08.
