Let's divide 819912 by 4
We're looking to find how many times 4 goes into 819912.

Let's proceed to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 4

Moving on to step 2:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Step 3:
4 goes into 19 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Subtract 16 from 19 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Let's proceed to step 4:
39 divided by 4 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 2049.0
Subtracting 36 from 39 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 4

Advancing to step 5:
If we divide 31 by 4, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 20497.0
Subtract 28 from 31 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Let's proceed to step 6:
If we divide 32 by 4, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 204978.0
If we subtract 32 from 32, 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.

Moving on to step 7:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 204978.0
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.

On to step 8:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 204978.0
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.

The final outcome is 204978.0, with a leftover of 0.0.
