648019 ÷ 4 
Let's see how many times 4 fits into 648019.

Let's proceed to step 1:
When dividing 6 by 4, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 4

Let's proceed to step 2:
When dividing 24 by 4, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 24 away from 24, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Advancing to step 3:
8 divided by 4 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Subtract 8 from 8 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Step 4:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1620.0
If we take 0 away from 0, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 4

Let's proceed to step 5:
If we divide 1 by 4, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 16200.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 4

Moving on to step 6:
The number 4 fits into 19 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 162004.0
The remainder is 3 after subtracting 16 from 19.
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 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 162004.7
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 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 162004.75
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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 162004.75
Subtracting 0 from 0 leaves us 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.

Going ahead to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 162004.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 162004.75 and a remainder of 0.0.
