386829 ÷ 39 
We want to figure out the number of times 386829 can be divided by 39.

Let's proceed to step 1:
The number 39 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 39

Step 2:
If we divide 38 by 39, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 39

Moving on to step 3:
When dividing 386 by 39, we get 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 351 from 386, we get 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 39

Advancing to step 4:
358 divided by 39 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 351 from 358 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 39

Moving on to step 5:
39 can be fit into 72 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 991.0
Deduct 39 from 72 and we're left with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 39

On to step 6:
If we divide 339 by 39, we get 8 and a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 9918.0
If we subtract 312 from 339, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
39 can be fit into 270 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 9918.6
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
When dividing 360 by 39, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 9918.69
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 39 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 9918.692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
39 goes into 120 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 9918.6923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 9918.6923
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 39, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 9918.692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
When dividing 270 by 39, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 9918.6923076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9918.69230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 9918.69230769 with a remaining 9e-09.
