Let's divide 508486 by 4
Our goal is to divide 508486 by 4.

Going ahead to step 1:
4 goes into 5 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 4 from 5 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Advancing to step 2:
10 divided by 4 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 2 after subtracting 8 from 10.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 4

Moving on to step 3:
4 can be fit into 28 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 28 from 28 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

Step 4:
4 divided by 4 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1271.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Advancing to step 5:
When dividing 8 by 4, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12712.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Going ahead to step 6:
4 goes into 6 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 127121.0
If we take 4 away from 6, we end up 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.

Step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 127121.5
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 127121.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 127121.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 127121.5, and the remainder is 0.0.
