Let's divide 383940 by 7
We want to divide 383940 by 7.

Step 1:
7 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 7

Step 2:
38 divided by 7 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 35 from 38 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 7

Moving on to step 3:
When dividing 33 by 7, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 28 from 33 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 7

On to step 4:
When dividing 59 by 7, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 548.0
If we subtract 56 from 59, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 7

On to step 5:
7 can be fit into 34 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 5484.0
The remainder is 6 after subtracting 28 from 34.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 7

Step 6:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 54848.0
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 54848.5
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 54848.57
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 54848.571
Subtracting 7 from 10 leaves us 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.

Advancing to step 10:
30 divided by 7 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 54848.5714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 54848.57142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 54848.571428
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 54848.5714285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 54848.57142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 54848.57142857, with a leftover of 1e-09.
