We're dividing 386309 by 39 
We want to divide 386309 by 39.

Moving on to step 1:
39 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 39

On to step 2:
When dividing 38 by 39, we get 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 39

Moving on to step 3:
386 divided by 39 is 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 351 from 386 to get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 39

Going ahead to step 4:
39 goes into 353 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 99.0
Deduct 351 from 353 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 39

Let's proceed to step 5:
20 divided by 39 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 990.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 39

Step 6:
39 goes into 209 5 times with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 9905.0
The remainder is 14 after subtracting 195 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
39 goes into 140 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 9905.3
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
39 goes into 230 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9905.35
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
39 can be fit into 350 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 9905.358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
39 goes into 380 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 9905.3589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
290 divided by 39 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 9905.35897
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 9905.358974
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
39 goes into 140 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 9905.3589743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
If we divide 230 by 39, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 9905.35897435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 9905.35897435 with a remainder of 3.5e-08.
