508457 ÷ 7 
We're looking to find how many times 7 goes into 508457.

On to step 1:
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: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 7

On to step 2:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 49 from 50 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Going ahead to step 3:
7 goes into 18 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we take 14 away from 18, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 7

Going ahead to step 4:
7 goes into 44 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0
If we take 42 away from 44, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 7

Moving on to step 5:
If we divide 25 by 7, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 7263.0
Subtract 21 from 25 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 7

Moving on to step 6:
The number 7 fits into 47 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 72636.0
If we take 42 away from 47, 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.

Advancing to step 7:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 72636.7
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.

On to step 8:
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: 72636.71
If we subtract 7 from 10, we get 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:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 72636.714
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.

Let's proceed to step 10:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 72636.7142
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.

Going ahead to step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 72636.71428
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.

Moving on to step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 72636.714285
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.

Going ahead to step 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 72636.7142857
Subtracting 49 from 50 leaves us 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 14:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 72636.71428571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 72636.71428571 with a balance of 3e-09.
