We divide 393508 by 7
We want to figure out the number of times 393508 can be divided by 7.

Advancing to step 1:
If we divide 3 by 7, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 7

Moving on to step 2:
When dividing 39 by 7, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 35 from 39 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 7

Advancing to step 3:
43 divided by 7 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 42 from 43, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 7

Advancing to step 4:
When dividing 15 by 7, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 562.0
Subtract 14 from 15 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

Moving on to step 5:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 5621.0
Deduct 7 from 10 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

Going ahead to step 6:
7 goes into 38 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 56215.0
The remainder is 3 after subtracting 35 from 38.
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 7:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 56215.4
Subtracting 28 from 30 leaves us 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.

On to step 8:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 56215.42
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.

Going ahead to step 9:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 56215.428
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.

Let's proceed to step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 56215.4285
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.

Going ahead to step 11:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 56215.42857
Deduct 49 from 50 and we're left 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.

Let's proceed to step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 56215.428571
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 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 56215.4285714
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.

Advancing to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 56215.42857142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 56215.42857142 with a balance of 6e-09.
