We're dividing 390948 by 39 
We want to figure out the number of times 390948 can be divided by 39.

Advancing to step 1:
39 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 39

Step 2:
If we divide 39 by 39, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 39 from 39.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 39

Going ahead to step 3:
0 divided by 39 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 39

Let's proceed to step 4:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 9, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 39

Going ahead to step 5:
When dividing 94 by 39, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1002.0
If we subtract 78 from 94, we get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 39

Let's proceed to step 6:
168 divided by 39 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 10024.0
If we take 156 away from 168, we end up 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.

Let's proceed to step 7:
39 can be fit into 120 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 10024.3
Subtract 117 from 120 to 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 8:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10024.3
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 10024.307
If we take 273 away from 300, we end up with 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 10:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 10024.3076
Subtracting 234 from 270 leaves us 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.

On to step 11:
360 divided by 39 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 10024.30769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
90 divided by 39 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 10024.307692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 10024.3076923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
39 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10024.3076923
Subtracting 0 from 30 leaves us 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.

The quotient of the division is 10024.3076923, and the remainder is 3e-08.
