Let's divide 502420 by 7
We want to divide 502420 by 7.

On to step 1:
If we divide 5 by 7, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 7

Going ahead to step 2:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 49 away from 50, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

Going ahead to step 3:
12 divided by 7 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 71.0
If we take 7 away from 12, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 7

Step 4:
If we divide 54 by 7, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 717.0
Subtracting 49 from 54 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 7

On to step 5:
The number 7 fits into 52 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 7177.0
Subtracting 49 from 52 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

Let's proceed to step 6:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 71774.0
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.

Step 7:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 71774.2
If we take 14 away from 20, we end up 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.

On to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 71774.28
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.

Advancing to step 9:
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: 71774.285
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.

Let's proceed to step 10:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 71774.2857
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.

Moving on to step 11:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 71774.28571
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.

Going ahead to step 12:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 71774.285714
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 13:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 71774.2857142
If we take 14 away from 20, we end up 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.

Moving on to step 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 71774.28571428
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.

The final result is 71774.28571428 with a remainder of 4e-09.
