Let's divide 403905 by 7
We want to divide 403905 by 7.

Going ahead to step 1:
4 divided by 7 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 7

Step 2:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 35 from 40 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 7

Moving on to step 3:
When dividing 53 by 7, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 57.0
If we take 49 away from 53, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 7

On to step 4:
7 goes into 49 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 577.0
The remainder is 0 after subtracting 49 from 49.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 7

Let's proceed to step 5:
7 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5770.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Let's proceed to step 6:
If we divide 5 by 7, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 57700.0
If we subtract 0 from 5, we 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.

Advancing to step 7:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 57700.7
If we subtract 49 from 50, we get 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 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 57700.71
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.

Moving on to step 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 57700.714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 57700.7142
Subtract 14 from 20 to get 6.
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 11:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 57700.71428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 57700.714285
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.

On to step 13:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 57700.7142857
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 57700.71428571
If we take 7 away from 10, 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.

After the division, we end up with 57700.71428571 and a remainder of 3e-09.
