We look at the division of 350393 by 7 
We want to figure out the number of times 350393 can be divided by 7.

On to step 1:
When dividing 3 by 7, we get 0 with 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.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 7

On to step 2:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 35 away from 35, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 7

Advancing to step 3:
The number 7 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 50.0
Subtract 0 from 0 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 7

Advancing to step 4:
3 divided by 7 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 500.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

On to step 5:
When dividing 39 by 7, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5005.0
The remainder is 4 after subtracting 35 from 39.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 7

Step 6:
7 goes into 43 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 50056.0
Deduct 42 from 43 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.

On to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 50056.1
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 50056.14
Subtract 28 from 30 to 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 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 50056.142
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.

Let's proceed to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 50056.1428
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.

On to step 11:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 50056.14285
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.

Advancing to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 50056.142857
Subtract 49 from 50 to 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 13:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 50056.1428571
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.

Advancing to step 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 50056.14285714
Deduct 28 from 30 and we're left 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.

In conclusion, the division gives 50056.14285714 with a balance of 2e-09.
