We divide 506420 by 7
Let's see how many times 7 fits into 506420.

On to step 1:
7 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 7

Going ahead to step 2:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 49 away from 50, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 7

Moving on to step 3:
If we divide 16 by 7, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 14 from 16, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 7

Step 4:
24 divided by 7 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 723.0
If we subtract 21 from 24, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 7

Let's proceed to step 5:
If we divide 32 by 7, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 7234.0
Subtract 28 from 32 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 7

Moving on to step 6:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 72345.0
If we take 35 away from 40, we end up with 5.
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 7:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 72345.7
If we take 49 away from 50, we end up 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.

Advancing to step 8:
7 goes into 10 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 72345.71
Deduct 7 from 10 and we're left 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 9:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 72345.714
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.

Going ahead to step 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 72345.7142
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 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 72345.71428
If we take 56 away from 60, we end up 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.

Advancing to step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 72345.714285
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.

Step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 72345.7142857
If we take 49 away from 50, we end up 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.

Step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 72345.71428571
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.

The final outcome is 72345.71428571, with a leftover of 3e-09.
